The key challenge for these analyses is the correction for detector distortions known as deconvolution or unfolding. In the case of binned cross section measurements, there are many tools for regularized matrix inversion where the matrix governs the detector response going from pre- to post-detector observables. In this paper, we show how normalizing flows and neural posterior estimation can be used for unfolding. This approach has many potential advantages, including implicit regularization from the neural networks and fast inference from amortized training. We demonstrate this approach using simple Gaussian examples as well as a simulated jet substructure measurement at the Large Hadron Collider. https://escholarship.org/uc/item/5mg3n583 Fri, 26 Jun 2026 00:00:00 +0000 Desai, Krish https://orcid.org/0000-0003-2559-8910 Nachman, benjamin Pan, jingjing Mikuni, Vinicius https://orcid.org/0000-0002-1579-2421 Torales Acosta, Fernando https://escholarship.org/uc/item/5bq0x1w6 A model-agnostic search for Beyond the Standard Model physics is presented, targeting final states with at least four light leptons (electrons or muons). The search regions are separated by event topology and unsupervised machine learning is used to identify anomalous events in the full 140 fb-1$$^{-1}$$ of proton–proton collision data collected with the ATLAS detector during Run 2. No significant excess above the Standard Model background expectation is observed. Model-agnostic limits are presented in each topology, along with limits on several benchmark models including vector-like leptons, wino-like charginos and neutralinos, or smuons. Limits are set on the flavourful vector-like lepton model for the first time. https://escholarship.org/uc/item/5bq0x1w6 Fri, 26 Jun 2026 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Alberghi, GL Albert, J Alberti, U Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, DR Allen, JS Allen, JF Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amezza, T Amidei, D Amini, B Amirie, K Amirkhanov, A Dos Santos, SP Amor Amos, KR Amperiadou, D An, S Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M https://escholarship.org/uc/item/4ft186gd In this work, we forecast the number of, and requirements on, N-body simulations needed to train hybrid effective field theory (HEFT) emulators for a range of use cases, using a hybrid of HMcode and perturbation theory as a surrogate model. Our accuracy goals, determined with careful consideration of statistical and systematic uncertainties, are 1% accurate in the high-likelihood range of cosmological parameters, and 2% accurate over a broader parameter space volume for k < 1 h Mpc-1 and z < 3. Focusing in part on the 8-parameter w 0 wa CDM+mν cosmological model, we find that < 225 simulations are required to meet our error goals over our wide parameter space, including models with rapidly evolving dark energy, given our simulation and emulator recommendations. For a more restricted parameter space volume, as few as 80 simulations are sufficient. We additionally present simulation forecasts for example use cases, and make the code used in our analyses publicly available.... https://escholarship.org/uc/item/4ft186gd Fri, 26 Jun 2026 00:00:00 +0000 Bartlett, Alexa https://orcid.org/0000-0002-3421-8724 DeRose, Joseph White, Martin https://orcid.org/0000-0001-9912-5070 https://escholarship.org/uc/item/2th9b7zj This paper presents the first observation of top-quark pair production in association with two photons ( t t ¯ γ γ ). The measurement is performed in the single-lepton decay channel using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider. The data correspond to an integrated luminosity of 140 fb − 1 recorded during Run 2 at a centre-of-mass energy of 13 TeV. The t t ¯ γ γ production cross section, measured in a fiducial phase space based on particle-level kinematic criteria for the lepton, photons, and jets, is found to be 2 . 42 − 0.53 + 0.58 fb , corresponding to an observed significance of 5.2 standard deviations. Additionally, the ratio of the production cross section of t t ¯ γ γ to top-quark pair production in association with one photon is determined, yielding ( 3 . 30 − 0.65 + 0.70 ) × 10 − 3 . https://escholarship.org/uc/item/2th9b7zj Fri, 26 Jun 2026 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M åkesson, T PA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Alberghi, GL Albert, J Alberti, U Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, H MJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, B MM Allen, JS Allen, JF Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, Z MK Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amezza, T Amidei, D Amini, B Amirie, K Amirkhanov, A Dos Santos, SP Amor Amos, KR Amperiadou, D An, S Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M Anulli, F Aoki, M https://escholarship.org/uc/item/9t8677x0 We demonstrate that novel limits on prompt axionlike particles (ALPs) in the hard-to-probe mass range near the neutral pion—the so-called pion chimney—may be obtained from recasting data taken by the J-PARC KOTO experiment, to search for .

Their Mellin moments can be computed on the lattice, but direct determinations using local operators, besides ⟨x⟩, face severe challenges from reduced hypercubic symmetry, limiting results to the lowest moments. A recently proposed method resolves these issues using gradient flow. We demonstrate the efficacy of this method by computing ratios of flavor nonsinglet pion PDF moments up to ⟨x^{5}⟩ on four lattice spacings at m_{π}≃411  MeV. The moments and reconstructed PDF agree quantitatively with recent phenomenological extractions. https://escholarship.org/uc/item/9mc8x1bm Thu, 25 Jun 2026 00:00:00 +0000 Francis, Anthony Fritzsch, Patrick Harlander, Robert V Karur, Rohith Kim, Jangho Kohnen, Jonas T Pederiva, Giovanni Pefkou, Dimitra A Rago, Antonio Shindler, Andrea Walker-Loud, André https://orcid.org/0000-0002-4686-3667 Zafeiropoulos, Savvas https://escholarship.org/uc/item/9dd2h139 The measurement of three-dimensional femtoscopic correlations between identical charged kaons (K±K±) produced in p–Pb collisions at center-of-mass energy per nucleon pair $$\sqrt{{s}_{\text{NN}}}=5.02$$ TeV with ALICE at the LHC is presented for the first time. This measurement, supplementary to those in pp and Pb–Pb collisions, allows understanding the particle-production mechanisms at different charged-particle multiplicities and provides information on the dynamics of the source of particles created in p–Pb collisions, for which a general consensus does not yet exist. It is shown that the measured source sizes increase with charged-particle multiplicity and decrease with increasing pair transverse momentum. These trends for K±K± are similar to the ones observed earlier in identical charged-pion and $${\text{K}}_{\text{s}}^{0}{\text{K}}_{\text{s}}^{0}$$ correlations in Pb–Pb collisions at various energies and in π±π± correlations in p–Pb collisions at $$\sqrt{{s}_{\text{NN}}}=5.02$$... https://escholarship.org/uc/item/9dd2h139 Thu, 25 Jun 2026 00:00:00 +0000 Acharya, S Agarwal, A Aglieri Rinella, G Aglietta, L Agnello, M Agrawal, N Ahammed, Z Ahmad, S Ahn, SU Ahuja, I Akindinov, A Akishina, V Al-Turany, M Aleksandrov, D Alessandro, B Alfanda, HM Alfaro Molina, R Ali, B Alici, A Alizadehvandchali, N Alkin, A Alme, J Alocco, G Alt, T Altamura, AR Altsybeev, I Alvarado, JR Andrei, C Andreou, N Andronic, A Andronov, E Anguelov, V Antinori, F Antonioli, P Apadula, N Aphecetche, L Appelshäuser, H Arata, C Arcelli, S Arnaldi, R Arneiro, JGMCA Arsene, IC Arslandok, M Augustinus, A Averbeck, R Averyanov, D Azmi, MD Baba, H Badalà, A Bae, J Baek, YW Bai, X Bailhache, R Bailung, Y Bala, R Balbino, A Baldisseri, A Balis, B Banoo, Z Barbasova, V Barile, F Barioglio, L Barlou, M Barman, B Barnaföldi, GG Barnby, LS Barreau, E Barret, V Barreto, L Bartels, C Barth, K Bartsch, E Bastid, N Basu, S Batigne, G Battistini, D Batyunya, B Bauri, D Bazo Alba, JL Bearden, IG Beattie, C Becht, P Behera, D Belikov, I Bell Hechavarria, ADC Bellini, F Bellwied, R Belokurova, S Beltran, LGE Beltran, YAV Bencedi, G Bensaoula, A Beole, S Berdnikov, Y Berdnikova, A Bergmann, L Besoiu, MG Betev, L Bhaduri, PP Bhasin, A https://escholarship.org/uc/item/9db1f55b We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios up to , using the gradient flow in lattice quantum chromodynamics (QCD). As a testing ground, we employ SU(3) isosymmetric gauge configurations generated by the OpenLat initiative with a pseudoscalar mass of . Our analysis uses four lattice spacings and a nonperturbatively improved action, enabling full control over the continuum extrapolation, and the limit of vanishing flow time, . The flowed ratios exhibit O( ) scaling across the ensembles, and the continuum-extrapolated results, matched to the scheme at using next-to-next-to-leading order matching coefficients, show only mild residual flow-time dependence. The resulting ratios, computed with a relatively small number of configurations, are consistent with phenomenological expectations for the pion’s valence distribution, with statistical uncertainties that are competitive with modern global fits.

The data was recorded at the Large Hadron Collider (LHC) during 2023, and corresponds to an integrated luminosity of 79 μb−1. Exclusive J/ψ candidates were selected with a dedicated track-sensitive trigger based on the ATLAS transition radiation tracker. The analysis involves reconstruction of the dimuon invariant mass based on muon tracks from the inner detector, as the muon transverse momentum range of interest precludes the use of the standard muon reconstruction and identification algorithms. Differential cross sections are measured as a function of J/ψ rapidity and are compared with theoretical predictions. After extrapolation to sNN=5.02$$ \sqrt{s_{\textrm{NN}}}=5.02 $$ TeV, they are also compared with previous measurements performed by other experiments using data from LHC Run 2.

We introduce the EEC jet functions and investigate the infrared behavior of both small-angle EECs and angle-integrated EECs by performing explicit one-loop calculations. The factorization and universality of the EECs in these processes are demonstrated. A matching scheme is proposed to smoothly connect kinematic regions where different scaling behaviors with jet energy are observed. In combination with the next-to-leading order correction, this matching provides a good description of the EEC data and simulations in high-energy annihilation. Predictions for DIS processes for future electron-ion collider kinematics are also presented. https://escholarship.org/uc/item/8k19p851 Thu, 25 Jun 2026 00:00:00 +0000 Guo, Yuxun Vogelsang, Werner Yuan, Feng https://orcid.org/0000-0001-9979-3853 Zhao, Wenbin https://orcid.org/0000-0001-8324-6134 https://escholarship.org/uc/item/6v7346g2 Networks of radiation detectors provide a platform for real-time radioactive source detection and identification in urban environments. Detection algorithms in these systems must adapt to naturally-occurring changes in background, which requires well-characterized relationships between precipitation events and their corresponding radiological signature. We present a quantitative and qualitative description of rain-induced radon progeny deposition events occurring in Chicago from September 2023 to February 2024. We measure ambient gamma radiation levels, precipitation rate, temperature, pressure, and relative humidity in a network of sensor nodes. For each identified precipitation period, we decompose spectra into static- and radon-associated components as defined by a non-negative matrix factorization (NMF) algorithm.

Such a final state might occur in gauge-mediated supersymmetric models where a pair of binos and higgsinos mix to form neutralinos, one of which decays into a photon plus a gravitino while the other decays into a Higgs boson, a Z boson or a photon, plus a gravitino. The search is performed using the full Run-2 data sample of 140 fb−1 of s=13$$ \sqrt{s}=13 $$ TeV proton-proton collisions collected by the ATLAS detector at the Large Hadron Collider. No significant excess of events is observed above the Standard Model prediction and model-dependent exclusion limits at the 95% confidence level are set. These limits are interpreted in terms of the masses of gauginos, which are excluded up to 1.2 TeV depending on their branching ratios, and on their branching ratios as a function of their mass. https://escholarship.org/uc/item/4bv7f3qf Thu, 25 Jun 2026 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abulaiti, Y Acharya, BS Ackermann, A Adam Bourdarios, C Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Alberghi, GL Albert, J Alberti, U Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Alexa, C Aleksandrov, IN Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JS Allen, JF Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Ambler, A Amelung, C Amerl, M Ames, CG Amezza, T Amidei, D Amini, B Amirie, K Amirkhanov, A Amor Dos Santos, SP Amos, KR Amperiadou, D An, S Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M Anulli, F Aoki, M Aoki, T https://escholarship.org/uc/item/3b15d2zv Is the usual treatment of axion dark matter as a classical field reliable? We show that the answer is subtle: the axion field could well be in a quantum state that has no complete classical description, but realistic detectors cannot tell the difference. To see this, we solve a fully quantum model of axion detection using quantum optics techniques. We show that intrinsically quantum effects are washed out by mode averaging or small amounts of noise, and significantly suppressed by the weakness of the axion coupling. Our Letter exemplifies that there should always be a classical analog for axion dark matter effects, extends to other wave (ultralight) dark-matter candidates, and gives a general method to compute the effects of exotic dark-matter states. https://escholarship.org/uc/item/3b15d2zv Thu, 25 Jun 2026 00:00:00 +0000 Bao, Yunjia Cheong, Dhong Yeon Rodd, Nicholas L https://orcid.org/0000-0003-3472-7606 Takach, Joey Wang, Lian-Tao Zhou, Kevin https://orcid.org/0000-0002-9810-3977 https://escholarship.org/uc/item/307288sk We demonstrate that quantum and classical radiation effects can become non-negligible for TeV-class beams propagating through plasma channels typical of staged plasma accelerators. Although the quantum nonlinearity parameter χe remains small under currently envisioned experimental conditions, the cumulative influence of radiation over long acceleration distances can lead to significant modifications to the beam’s energy spread, emittance, and polarization. Our analytic models, validated by particle-in-cell simulations, highlight that for standard Gaussian beams, the orbit-induced energy spread dominates over quantum stochastic effects but can be mitigated by tailoring the beam profile, for example, through ring-shaped transverse distributions. In regimes where the radiation reaction approaches the accelerating force, the emittance may be cooled, forming distinctive ring-shaped phase-space structures. Finally, we analyze the influence of the radiation effect on spin transport inside... https://escholarship.org/uc/item/307288sk Thu, 25 Jun 2026 00:00:00 +0000 Qian, Qian Seipt, D Ma, Yong Bulanov, SS https://orcid.org/0000-0002-9861-9391 Schroeder, CB Thomas, AGR https://escholarship.org/uc/item/17f8n6j3 The top-quark mass is measured using top-quark decays producing an isolated lepton and J/ψ meson reconstructed in its μ+μ− decay mode. The data sample was recorded with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of s=13$$ \sqrt{s}=13 $$ TeV during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. The measurement is based on the invariant mass m(ℓμ+μ−) of the system made of the isolated lepton ℓ from the W boson decay and the non-isolated μ+μ− pair from a J/ψ decay of a b-hadron, exploiting its sensitivity to the top-quark mass. An unbinned maximum-likelihood fit to the m(ℓμ+μ−) distribution is performed to extract the top-quark mass. The top-quark mass is measured to be mtop = 172.17 ± 0.80 (stat) ± 0.81 (syst) ± 1.07 (recoil) GeV, with a total uncertainty of 1.56 GeV. The third uncertainty arises from changing the dipole parton shower gluon-recoil scheme used in top-quark decays. https://escholarship.org/uc/item/17f8n6j3 Thu, 25 Jun 2026 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abulaiti, Y Acharya, BS Ackermann, A Adam Bourdarios, C Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Alberghi, GL Albert, J Alberti, U Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Alexa, C Aleksandrov, IN Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, DR Allen, JS Allen, JF Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Ambler, A Amelung, C Amerl, M Ames, CG Amezza, T Amidei, D Amini, B Amirie, K Amirkhanov, A Amor Dos Santos, SP Amos, KR Amperiadou, D An, S Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M Anulli, F https://escholarship.org/uc/item/0rz293xt We report improved measurements of the all flavor astrophysical neutrino spectrum with IceCube by combining complementary neutrino samples in two independent analyses. Both analyses show evidence of a harder spectrum at energies below ∼30  TeV compared to higher energies where the spectrum is well characterized by a power law. The spectrum is better described by a log parabola or a broken power law, the latter being the preferred model. Both, however, reject a single power law over an energy range 5 TeV-10 PeV with a significance >4σ, providing new constraints on properties of cosmic neutrino sources. https://escholarship.org/uc/item/0rz293xt Thu, 25 Jun 2026 00:00:00 +0000 Abbasi, R Ackermann, M Adams, J Agarwalla, SK Aguilar, JA Ahlers, M Alameddine, JM Ali, S Amin, NM Andeen, K Arguelles, C Ashida, Y Athanasiadou, S Axani, SN Babu, R Bai, X Baines-Holmes, J V., A Balagopal Barwick, SW https://orcid.org/0000-0003-2050-6714 Bash, S Basu, V Bay, R Beatty, JJ Tjus, J Becker Behrens, P Beise, J Bellenghi, C Benkel, B BenZvi, S Berley, D Bernardini, E Besson, DZ Blaufuss, E Bloom, L Blot, S Bodo, I Bontempo, F Motzkin, JY Book Meneguolo, C Boscolo Boser, S Botner, O Bottcher, J Braun, J Brinson, B Brisson-Tsavoussis, Z Burley, RT Butterfield, D Campana, MA Carloni, K Carpio, J Chattopadhyay, S Chau, N Chen, Z Chirkin, D Choi, S Clark, BA Coleman, A Coleman, P Collin, GH Borja, DA Coloma Connolly, A Conrad, JM Corley, R Cowen, DF De Clercq, C DeLaunay, JJ Delgado, D Delmeulle, T Deng, S Desiati, P de Vries, KD de Wasseige, G DeYoung, T Diaz-Velez, JC DiKerby, S Dittmer, M Domi, A Draper, L Dueser, L Durnford, D Dutta, K DuVernois, MA Ehrhardt, T Eidenschink, L Eimer, A Eller, P Ellinger, E Elsasser, D Engel, R Erpenbeck, H Esmail, W Eulig, S Evans, J Evenson, PA Fan, KL Fang, K Farrag, K Fazely, AR Fedynitch, A Feigl, N https://escholarship.org/uc/item/7j80b1zm For LHC Run 3, the ALICE Time Projection Chamber was upgraded to operate in continuous readout mode. Interaction rates of up to 50 kHz in Pb-Pb collisions require real-time processing of more than 3 TB s-1 of raw detector data. This requirement is met by a custom FPGA-based processing pipeline that performs the complete front-end data treatment fully in-stream, including common-mode correction, pedestal subtraction, ion-tail filtering, zero suppression, and dense data packing. A central element of the design is a highly parallel common-mode correction algorithm operating directly on the streaming data. It robustly identifies signal-free readout channels on a time-bin basis and applies pad-dependent scaling to compensate for local variations in capacitive coupling in the GEM readout. In combination with pedestal subtraction and ion-tail filtering, this enables accurate baseline restoration under extreme high-occupancy conditions, preventing signal loss while efficiently suppressing... https://escholarship.org/uc/item/7j80b1zm Wed, 24 Jun 2026 00:00:00 +0000 Alme, J Alt, T Andrei, C Anguelov, V Appelshäuser, H Arslandok, M Averbeck, R Ball, M Barnaföldi, GG Becht, P Bellwied, R Berdnikova, A Blidaru, B Boldizsár, L Bratrud, L Braun-Munzinger, P Bregant, M Britton, CL Büsching, H Caines, H Chatzidaki, P Christiansen, P Cormier, TM Döpper, L Ehlers, R https://orcid.org/0000-0002-3897-0876 Fabbietti, L Flor, F Gaardhøje, JJ Munhoz, MG Garabatos, C Gasik, P Gera, Á Glässel, P Grünwald, N Gündem, T Gunji, T Hamagaki, H Harris, JW Hauer, P Hellbär, E Helstrup, H Herghelegiu, A Herrera, HD Hernandez Hou, Y Hughes, C Ivanov, M Jäger, J Ji, Y Jung, J Jung, M Ketzer, B Kirsch, S Kleiner, M Knospe, AG Korwieser, M Kowalski, M Lautner, L Lesch, M Lippmann, C Mantzaridis, G Majka, RD Marin, A Markert, C Masciocchi, S Matyja, A Meres, M Mihaylov, DL Miśkowiec, D Munzer, RH Murakami, H Münning, K Nassirpour, A Nattrass, C Nielsen, BS Noije, WAV Da Silva, AC Oliveira Oskarsson, A Oyama, K Österman, L Pachmayer, Y Paić, G Petris, M Petrovici, M Planinic, M Rasson, J Read, KF Rehman, A Renfordt, R Riedel, A Røed, K Röhrich, D Rubio, E Rusu, A Sadhu, S Sanches, BCS Schambach, J Schmah, A Schmidt, C Schmier, A Schweda, K https://escholarship.org/uc/item/7gh6f6vg The IceCube Upgrade is an extension of the existing IceCube Neutrino Observatory and will be deployed in the 2025–2026 austral summer. It will significantly improve the sensitivity of the detector to atmospheric neutrino oscillations. The existing 86-string IceCube array contains a dense in-fill known as DeepCore which is optimized to measure neutrinos with energies down to a few GeV. The IceCube Upgrade will consist of seven new densely instrumented strings placed within the DeepCore volume to further enhance the performance in the GeV energy range. The additional strings will feature new optical modules, each containing multiple photomultiplier tubes (PMTs), in contrast to the existing modules that each contain a single PMT. This will more than triple the number of PMT channels with respect to the current IceCube configuration, allowing for improved detection efficiency and reconstruction performance at GeV energies.

While efforts have largely focused on on-shell double- and single-Higgs production in proton-proton collisions, off-shell Higgs production has also been proposed as a valuable complementary probe. In this article, we design a hybrid neural simulation-based inference (NSBI) approach to construct a likelihood of the Higgs signal incorporating modifications from the Standard Model effective field theory (SMEFT), relevant background processes, and quantum interference effects. It leverages the training efficiency of matrix-element-enhanced techniques, which are vital for robust SMEFT applications, while also incorporating the practical advantages of classification-based methods for effective background estimates.

For a number of typical fission cases, samples of 104 shape evolutions are generated by Langevin simulation and, subsequently, for each such evolution, the nucleon exchange transport theory previously developed for damped nuclear reactions is used to obtain the development of the fragment spin-spin distribution within the Fokker-Planck transport framework. The characteristic evolution of both parallel and perpendicular spin components is discussed. A common feature is that the rotational modes fall out of equilibrium before scission when the temperature rises rapidly while the concurrent shrinking of the neck suppresses further exchange. A number of fission observables are extracted from the event ensembles: the distribution of the magnitude of the fragment spin and its orientation relative to the fission axis, as well as the correlation between the two spins and the distribution... https://escholarship.org/uc/item/3wg2c91q Wed, 24 Jun 2026 00:00:00 +0000 Randrup, Jørgen Nadtochy, Pavel Schmitt, Christelle Mazurek, Katarzyna https://escholarship.org/uc/item/36h516fc The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks and cascade events from neutrino interactions. We present two analyses sensitive to neutrino events in the energy range 1 TeV to 10 PeV, using more than 10 years of IceCube data. Both analyses consistently reject a neutrino spectrum following a single power-law with a significance of >4σ in favor of a broken power law. We describe the methods implemented in the two analyses, the spectral constraints obtained, and the validation of the robustness of the results. Additionally, we report the detection of a muon neutrino in the medium energy starting events sample, or MESE, with an energy of 11.4-2.53+2.46 PeV, the highest energy neutrino observed by IceCube to date.

The majority of the analysis was conducted on photometric catalogs that had their absolute zero-points randomized to mask information on distance. The new F115W TRGB distances, anchored by the geometric maser distance to NGC 4258, agree well with our previously derived Hubble Space Telescope (HST) TRGB distances, differing by only 1% on average and 4% on a per-galaxy basis. The color-corrected F115W TRGB is therefore equally precise a method of distance measurement as, and offers unique advantages over, its color-insensitive, I-band counterpart. We use these distances to update four published H0 calibrations and evaluate how different SN analyses, both within and across independent groups, yield different H0 values.

Experiments are currently being built to search for these signals. Here we analyze the minimal model of quantum gravity at low energies—the usual effective quantum field theory of gravitons—and show that it unambiguously predicts an unobservably small variation in the measured interferometer length . In particular, there are no divergences signaling a breakdown of this calculation in the low energy regime. Thus, detection of a large, gravitationally induced length variation would signal a severe breakdown of effective quantum field theory in low energy quantum gravity. https://escholarship.org/uc/item/2n1554pn Thu, 18 Jun 2026 00:00:00 +0000 Carney, Daniel https://orcid.org/0000-0002-4269-8342 Karydas, Manthos Sivaramakrishnan, Allic https://escholarship.org/uc/item/1x7081zj We perform a multiprobe analysis combining cosmic microwave background (CMB) data from and the Atacama Cosmology Telescope (ACT), ACT CMB lensing, and large-scale structure (LSS) measurements from the Dark Energy Spectroscopic Instrument (DESI), including DESI Legacy Imaging Survey (LS) galaxies and baryon acoustic oscillations (BAOs).

We observe that heavy Baryon chiral perturbation theory does not provide an unambiguous prediction for the sign of the FV correction, which is not surprising when one also considers large- constraints on the axial couplings. We further show that nonmonotonic FV corrections are naturally allowed when one considers either including explicit -resonance degrees of freedom or one works to higher orders in the chiral expansion. We investigate the potential impact of these FV corrections with a precision study of using models of FV corrections that are monotonic and nonmonotonic. Using lattice QCD data that is approximately at the 1% level of precision, we do not see significant evidence of nonmonotonic corrections.

At leading order in the QCD coupling, the di-jet cross-section exhibits transverse-momentum dependent (TMD) factorisation, with a gluon diffractive TMD distribution (DTMD) which is controlled by gluon saturation and describes the transverse-momentum imbalance between the produced jets. The next-to-leading corrections generate the various quantum evolutions of the diffractive gluon distribution. We focus on the Collins-Soper-Sterman (CSS) evolution which describes the change in the gluon DTMD when increasing the “hard scale” (the typical transverse momentum of the di-jets).

The subsystem provided essential mid-rapidity particle identification for the fixed-target portion of phase II of the STAR beam energy scan. The fixed-target program allowed the experiment to access center-of-mass energies from s N N = 3 . 0 GeV to s N N = 7 . 7 GeV, not accessible by colliding beams. The system’s detectors and readout electronics were designed for the CBM experiment at FAIR and adapted for use at STAR.

State-of-the-art techniques are based on machine learning and require training data with events that have been matched using simulations with truth information. In nature, there is no unique matching between partons and final state objects due to the properties of the strong force and due to acceptance effects. We propose a new approach to parton labeling that circumvents these challenges by recycling regression models. The final state objects that are most relevant for a regression model to predict the properties of a particular top quark are assigned to said parent particle without having any parton-matched training data. This approach is demonstrated using simulated events with top quarks and outperforms the widely-used χ2$$\chi ^2$$ method. https://escholarship.org/uc/item/8wq0d9kj Tue, 16 Jun 2026 00:00:00 +0000 Qiu, Shikai Han, Shuo https://orcid.org/0000-0001-8383-7348 Ju, Xiangyang Nachman, Benjamin Wang, Haichen https://escholarship.org/uc/item/7zt1t47j Machine learning (ML)-based algorithms play increasingly important roles in almost all aspects of the data analyses in ATLAS, including detector simulations, event reconstructions, and data analyses.

The map is expressed in a factorized Lie-algebraic (axis-angle) form, making it straightforward to determine the corresponding $SU(2)$ or quaternion representation. To facilitate numerical implementation, the Lie generators are expressed as functions of the six phase space variables commonly used for charged particle transport in $s$-based tracking codes.

The upcoming LEGEND-1000 experiment (Large Enriched Germanium Experiment for Neutrinoless double-beta Decay) constitute a ton-scale array of several hundred high-purity germanium (HPGe) detectors enriched in 76Ge, the isotope of interest. It aims to reach a sensitivity beyond $10\mathbf {^{28}}$ years on the $\mathbf {0}\boldsymbol { u }\boldsymbol {\beta }\boldsymbol {\beta }$ decay half-life of 76Ge, necessitating an order of magnitude reduction in background with respect to the state of the art. This will require the implementation of a dedicated application specific integrated circuit (ASIC) preamplifier that will significantly lower background contribution compared to the conventional low-mass front end (LMFE) employed in the Majorana Demonstrator and LEGEND-200 experiments... https://escholarship.org/uc/item/58z6z10q Fri, 5 Jun 2026 00:00:00 +0000 Drobizhev, Alexey Gnani, Dario https://orcid.org/0000-0003-0464-9176 Grace, Carl Matsumoto, Ryutaro Papadopoulou, Aikaterini https://orcid.org/0000-0001-9440-6076 Poon, Alan https://orcid.org/0000-0003-2684-6402 Schlueter, Lisa Schuetz, Ann-Kathrin Wright, Will Turqueti, Marcos https://orcid.org/0000-0002-3892-1353 https://escholarship.org/uc/item/9xd1v31s As the world becomes increasingly reliant on interconnected digital infrastructure, the urgency to understand and manage cyber conflict increases. Policy-makers have long sought to translate concepts used in the nuclear and conventional domains to state competition in the cyber domain—not least whether the concept of deterrence that underpins the nuclear realm travels. Unfortunately, analysts face two difficult challenges associated with analyzing cyber deterrence. First, using the historical record for empirical data, scholars are only able to observe deterrence failure—with no guarantee that the observed instances of deterrence failure represent a complete set. Second, the “cyber” domain is interminably difficult to both analyze and model—with similar selection effects associated with which types of cyber attacks are detected. As evidenced by our study leveraging a new experimental wargame, TANTALUS, wargaming methods can solve some of these challenges.

The analysis uses the 140 fb − 1 of Run-2 data collected at s = 13 TeV by the ATLAS experiment in 2015–2018. The results of the analysis are interpreted in the context of three benchmark models covering masses from 0.1 to 2.2 TeV and a range of mean proper lifetimes times the speed of light from 1 to 10 000 mm. The first model is a generic Z′ boson pair-produced by a new heavy scalar, with the Z′ decaying into lepton pairs. The remaining two models are R-parity violating supersymmetric models in which the lightest neutralino χ ˜ 1 0 decays into ℓ + ℓ ′ − ν ( ℓ , ℓ ′ = e , μ).

This analysis uses dijets as a proxy for the parton–parton scattering configuration, correlating it with event geometry estimators, namely the energy deposited in the Zero-Degree Calorimeter and the transverse energy recorded in the Forward Calorimeter in the Pb-going direction. The analysis uses data recorded by the ATLAS detector at the Large Hadron Collider with a nucleon–nucleon center-of-mass energy of 8.16 TeV, corresponding to an integrated luminosity of 56 nb − 1 .

This volume outlines how FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model. The report reviews the experimental opportunities offered by the staged implementation of FCC, beginning with an electron-positron collider (FCC-ee), operating at several centre-of-mass energies, followed by a hadron collider (FCC-hh). Benchmark examples are given of the expected physics performance, in terms of precision and sensitivity to new phenomena, of each collider stage. Detector requirements and conceptual designs for FCC-ee experiments are discussed, as are the specific demands that the physics programme imposes on the accelerator in the domains of the calibration of the collision... https://escholarship.org/uc/item/86w380qt Wed, 3 Jun 2026 00:00:00 +0000 Benedikt, M Zimmermann, F Auchmann, B Bartmann, W Burnet, JP Carli, C Chancé, A Craievich, P Giovannozzi, M Grojean, C Gutleber, J Hanke, K Henriques, André Janot, P Lourenço, C Mangano, M Otto, T Poole, J Rajagopalan, S Raubenheimer, T Todesco, E Ulrici, L Watson, T Wilkinson, G Azzi, P Bernardi, G Blondel, A Boscolo, M d’Enterria, D Dam, M de Blas, J Francois, B Freitas, A Ganis, G Keintzel, J Klute, M McCullough, M Monni, PF Palla, F Perez, E Pleier, M-A Riegler, W Sefkow, F Selvaggi, M Abada, A Abbrescia, M Abdolmaleki, H Abidi, SH Abramov, A Adam, C Ady, M Adz̆ić, PR Agapov, I Aguglia, D Ahmed, I Aiba, M Aielli, G Akan, T Akchurin, N Akturk, D Al-Thakeel, M Alberghi, GL Maestre, J Alcaraz Aleksa, M Aleksan, R Alharthi, F Alimena, J Alimenti, A Alioli, S Alix, L Allanach, BC Allwicher, L Altintas, AA Altınlı, M Alviggi, M Ambrosio, G Amhis, Y Amiri, A Ammirabile, G Andeen, T André, KDJ Andrea, J Andreazza, A Andreini, M Andriollo, T Angel, L Angelucci, M Antusch, S Anwar, MN Apolinário, L Apollinari, G Appleby, RB Apresyan, A Apyan, Aram Apyan, Armen Arbey, A Argiento, B Ari, V Arias, S Alonso, B Arias https://escholarship.org/uc/item/4hf351ws Surrogate distributed radiological sources III: quantitative distributed source reconstructions https://escholarship.org/uc/item/4hf351ws Wed, 3 Jun 2026 00:00:00 +0000 Vavrek, Jayson R https://orcid.org/0000-0002-6809-9380 Lee, Jaewon https://orcid.org/0000-0002-2744-4264 Salathe, Marco https://orcid.org/0000-0003-2484-4606 Bandstra, Mark S https://orcid.org/0000-0002-6403-7895 Hellfeld, Daniel https://orcid.org/0000-0001-6252-2929 Quiter, Brian J https://orcid.org/0000-0001-7001-7455 Joshi, Tenzing HY https://orcid.org/0000-0003-0846-7871 https://escholarship.org/uc/item/4b81v8tf A measurement of the inclusive production cross section of isolated prompt photons in proton-antiproton collisions at center-of-mass energy s=1.96 TeV is presented.

Each LD was assembled with a large cubic light-emitting crystal (45 mm side) using the recently developed CROSS mechanical structure. The detector array was operated at milli-Kelvin temperatures in a pulse-tube cryostat at the Canfranc underground laboratory in Spain. We achieved good performance with scintillating bolometers from CROSS, made of Li2 100MoO4 crystals and used as reference detectors of the setup, and with all LDs tested (except for a single device that encountered an electronics issue). No leakage current was observed for 8 LDs with an electrode bias up to 100 V. Operating the LDs at an 80 V electrode bias applied in parallel, we obtained a gain of around 9 in the signal-to-noise ratio of these devices,... https://escholarship.org/uc/item/3386p4jq Wed, 3 Jun 2026 00:00:00 +0000 Armatol, A Barabash, AS Baudin, D Berest, V Beretta, M Bergé, L Buchynska, M Calvo-Mozota, JM Capelli, C Carniti, P Chapellier, M Dafinei, I Danevich, FA Dixon, T Drobizhev, A Dumoulin, L Ferri, F Gallas, A Giuliani, A Gotti, C Gras, Ph Ianni, A Imbert, L Khalife, H Kobychev, VV Konovalov, SI Loaiza, P de Marcillac, P Marnieros, S Marrache-Kikuchi, CA Martinez, M Mazzucato, E Nones, C Olivieri, E de Solórzano, A Ortiz Pageot, M Peinaud, Y Pérez, V Pessina, G Poda, DV Rosier, P Scarpaci, JA Schmidt, B Tretyak, VI Umatov, VI Zarytskyy, MM Zolotarova, A https://escholarship.org/uc/item/2mw7551c Empowering Minds: Exploring the Impact of the Contemporary Physics Education Project https://escholarship.org/uc/item/2mw7551c Wed, 3 Jun 2026 00:00:00 +0000 Barnett, R Michael https://orcid.org/0000-0002-7210-9887 Harper, Cheryl Melnik, Glen Norris, Peggy https://escholarship.org/uc/item/8vm1k5vr Recently, IceCube reported neutrino emission from the Seyfert galaxy NGC 1068. Using 13.1 yr of IceCube data, we present a follow-up search for neutrino sources in the northern sky. NGC 1068 remains the most significant neutrino source among 110 preselected gamma-ray emitters while also being spatially compatible with the most significant location in the northern sky. Its energy spectrum is characterized by an unbroken power-law with spectral index γ = 3.4 ± 0.2. Consistent with previous results, the observed neutrino flux exceeds its gamma-ray counterpart by at least 2 orders of magnitude. Motivated by this disparity and the high X-ray luminosity of the source, we selected 47 X-ray-bright Seyfert galaxies from the Swift/BAT spectroscopic survey that were not included in the list of gamma-ray emitters.

The QGP forms in ultrarelativistic heavy-ion collisions. Anisotropic flow coefficients, quantifying the azimuthal expansion of produced matter, probe QGP properties. Flow measurements in high-energy heavy-ion collisions show a distinctive grouping of anisotropic flow for baryons and mesons at intermediate transverse momentum – a feature associated with flow imparted at the quark level, confirming QGP existence. The observation of QGP-like features in proton–proton and proton–ion collisions has sparked debate about QGP formation in smaller systems. For the first time, we demonstrate the distinctive grouping of anisotropic flow for baryons and mesons in high-multiplicity proton–lead and proton–proton collisions at the Large Hadron Collider (LHC).

The goal of these methods is to produce fast and accurate reconstruction methods to aid future analyses of baryonic feedback using the SZ effect. The first approach employs a Gaussian process emulator to model the SZ quantities via a transfer function, while the second utilizes hybrid effective field theory (HEFT) to reproduce these quantities within the simulation. Our analysis involves comparing both methods to the true MillenniumTNG optical depth and Compton-y fields using several metrics, including the cross-correlation coefficient, power spectrum, and power spectrum error.

Only a small fraction of the observed astrophysical neutrinos can be explained by known sources. Neutrino production is thought to occur in energetic environments that are ultimately powered by the gravitational collapse of dense regions of the large-scale mass distribution in the universe. Whatever their identity, neutrino sources likely trace this large-scale mass distribution. The clustering of neutrinos with a tracer of the large-scale structure may provide insight into the distribution of neutrino sources with respect to redshift and the identity of neutrino sources.

This article introduces the ­concept of physical differential fuzz testing as a challenge-response-style tamper indicator that can holistically and simultaneously test various components in a cyber-physical system. This concept is then applied to authenticating the radiation measurement equipment in nuclear weapon verification systems and conducting demonstration fuzz testing measurements with a sodium iodide (NaI) gamma ray spectrometer. We show that physical differential fuzz testing can detect two types of tamper attempts, and conclude that it is a promising framework for authenticating future cyber-physical systems in nuclear arms control, safeguards, and beyond. https://escholarship.org/uc/item/96m9b586 Thu, 21 May 2026 00:00:00 +0000 Vavrek, Jayson R https://orcid.org/0000-0002-6809-9380 Zhou, Luozhong Boverhof, Joshua https://orcid.org/0000-0003-2553-6613 Heymann, Elisa R Miller, Barton P Peisert, Sean https://orcid.org/0000-0003-3566-9719 https://escholarship.org/uc/item/5f61q0gf The structural biology method of X-ray footprinting mass spectrometry (XFMS) is available at two national synchrotron beamlines in the USA: one at the Advanced Light Source (ALS) on the West Coast and the other at the National Synchrotron Light Source II on the East Coast. XFMS is a solution-state technique that utilizes oxidative modifications of proteins at micromolar concentrations in aqueous buffer to extract structural information. X-rays are employed to generate hydroxyl radicals in situ, which covalently modify specific protein side chains. These modifications are subsequently quantified using liquid chromatography and mass spectrometry. Ratiometric changes in modification levels between two protein states (e.g. with and without ligand) generate a relative solvent accessibility map of the protein pairs, which serves to reveal structural features.

We extend our prior studies to third- and fourth-order cumulants in both coordinate- and momentum-space acceptances and integrated correlation functions (factorial cumulants). We find that, even near the critical point, non-Gaussian cumulants equilibrate on timescales comparable to those of the second-order cumulants, but show stronger finite-size effects. The presence of interactions and of the critical point leads to strong deviations of the cumulants from the ideal-gas baseline in coordinate space; these deviations are expected to persist in momentum space in the presence of collective expansion. In particular, the kurtosis becomes strongly negative, , on the crossover side of the critical point.

This suggests that neutrinos are produced near the supermassive black hole, where the radiation density is high enough to obscure gamma rays. We use a set of muon neutrinos with interaction vertices inside the detector, which have good sensitivity to sources in the southern sky, from IceCube data recorded between 2011 and 2021.

Using the correlations between keV X-rays and TeV neutrinos predicted by disk–corona models, and assuming production characteristics similar to NGC 1068, a collective neutrino signal search reveals an excess of 6.7−3.2+4.0 events, which is inconsistent with... https://escholarship.org/uc/item/6333c24f Fri, 15 May 2026 00:00:00 +0000 Abbasi, R Ackermann, M Adams, J Agarwalla, SK Aguilar, JA Ahlers, M Alameddine, JM Ali, S Amin, NM Andeen, K Argüelles, C Ashida, Y Athanasiadou, S Axani, SN Babu, R Bai, X Baines-Holmes, J V., A Balagopal Barwick, SW https://orcid.org/0000-0003-2050-6714 Bash, S Basu, V Bay, R Beatty, JJ Tjus, J Becker Behrens, P Beise, J Bellenghi, C Benkel, S BenZvi, S Berley, D Bernardini, E Besson, DZ Blaufuss, E Bloom, L Blot, S Bodo, I Bontempo, F Motzkin, JY Book Meneguolo, C Boscolo Böser, S Botner, O Böttcher, J Braun, J Brinson, B Brisson-Tsavoussis, Z Burley, RT Butterfield, D Campana, MA Carloni, K Carpio, J Chattopadhyay, S Chau, N Chen, Z Chirkin, D Choi, S Clark, BA Coleman, P Collin, GH Borja, DA Coloma Connolly, A Conrad, JM Cowen, DF De Clercq, C DeLaunay, JJ Delgado, D Delmeulle, T Deng, S Desiati, P de Vries, KD de Wasseige, G DeYoung, T Díaz-Vélez, JC DiKerby, S Ding, T Dittmer, M Domi, A Draper, L Dueser, L Durnford, D Dutta, K DuVernois, MA Ehrhardt, T Eidenschink, L Eimer, A Eldridge, C Eller, P Ellinger, E Elsässer, D Engel, R Erpenbeck, H Esmail, W Eulig, S Evans, J Evenson, PA Fan, KL Fang, K Farrag, K Fazely, AR Fedynitch, A Feigl, N https://escholarship.org/uc/item/2zm1z7hn Abstract The electroproduction of $\eta ^{\prime }$ mesons from a $\mathrm{^{1}H}$ target at $W=\mathrm{2.13~GeV}$, $Q^{2} = 0.46~\left( \mathrm{GeV/}c\right)^{2}$, and $\cos \theta ^{\mathrm{CM}}_{\gamma ^{*}\eta ^{\prime }} \approx -1$ has been experimentally measured. The differential cross section of virtual photoproduction has been obtained as $4.4 \pm 0.8 ~\left( \mathrm{stat.} \right) \pm 0.4 ~\left( \mathrm{sys.} \right)~ \mathrm{nb/sr}$ in the One-Photon-Exchange Approximation. This value is one-sixth of that of real photoproduction at backward angles. A comparison with newly developed isobar model calculations not only shows the validity of the theoretical framewark employed, but also imposes new constraints on coupling strength between the $\eta ^{\prime }p$ final state and nucleon resonances. https://escholarship.org/uc/item/2zm1z7hn Fri, 15 May 2026 00:00:00 +0000 Akiyama, T Bydžovský, P Gogami, T Itabashi, K Nagao, S Nakamura, SN Okuyama, K Pandey, B Skoupil, D Suzuki, KN Tang, L Abrams, D Androic, D Aniol, K Gayoso, C Ayerbe Bane, J Barcus, S Barrow, J Bellini, V Bhatt, H Bhetuwal, D Biswas, D Camsonne, A Castellanos, J Chen, J-P Chen, J Covrig, S Chrisman, D Cruz-Torres, R Das, R Fuchey, E Gnanvo, K Garibaldi, F Gautam, T Gomez, J Gueye, P Hague, TJ https://orcid.org/0000-0003-1288-4045 Hansen, O Henry, W Hauenstein, F Higinbotham, DW Hyde, CE Kaneta, M Keppel, C Kutz, T Lashley-Colthirst, N Li, S Liu, H Mammei, J Markowitz, P McClellan, RE Meddi, F Meekins, D Michaels, R Mihovilovič, M Moyer, A Nguyen, D Nycz, M Owen, V Palatchi, C Park, S Petkovic, T Premathilake, S Reimer, PE Reinhold, J Riordan, S Rodriguez, V Samanta, C Santiesteban, SN Sawatzky, B Širca, S Slifer, K Su, T Tian, Y Toyama, Y Trnková, D Uehara, K Urciuoli, GM Votaw, D Williamson, J Wojtsekhowski, B Wood, SA Yale, B Ye, Z Zhang, J Zheng, X https://escholarship.org/uc/item/7ng4n670 The exploration of the Quantum Chromodynamics (QCD) phase diagram is a central goal of relativistic heavy-ion collision experiments. This review focuses on the role of fluctuations and correlations as sensitive probes of the phase structure. We discuss theoretical advancements and experimental methodologies employed to map the QCD phase diagram, highlighting constraints derived from both lattice QCD calculations and existing experimental data. Key observables, such as cumulants and factorial cumulants of conserved charges (e.g., net proton, net charge), are explored as promising signatures of phase transitions and the QCD critical point. We discuss how these quantities are measured experimentally and compared with theoretical predictions, addressing challenges and best practices for meaningful comparisons. Special attention is given to predictions and current experimental results at high baryon density, including recent findings from the STAR collaboration at RHIC.

A powerful means of unlocking this knowledge lies in measuring the auto-power spectrum and/or the cross-power spectrum of the galaxy density and momentum fields, followed by the estimation of cosmological parameters based on these spectrum measurements. In this study, we generalize the cross-power spectrum model to accommodate scenarios in which the density and momentum fields are derived from distinct galaxy surveys. The growth rate of the large-scale structures of the Universe, commonly represented as fσ 8 , was extracted by jointly fitting the monopole and quadrupole moments of the auto-density power spectrum, the monopole of the auto-momentum power spectrum, and the dipole of the cross-power spectrum.

In this paper, a new method is explored for studying vector-meson global spin alignment in heavy-ion collisions by examining the two-dimensional (2D) polar and azimuthal angle distribution. This method allows simultaneous extraction of ρ00 and off-diagonal spin density matrix elements (SDMEs), providing unique access to local quark-antiquark spin correlations and spin hydrodynamics in quark-gluon plasma. The new 2D method also removes potential biases from nonzero off-diagonal SDMEs on ρ00 with the 1D method. A detailed procedure to correct for detector acceptance and resolution effects is also presented and validated by simulation studies. https://escholarship.org/uc/item/0tc8z144 Thu, 14 May 2026 00:00:00 +0000 Wilks, Gavin Sun, Xu Ye, Zhenyu https://orcid.org/0000-0001-6091-6772 https://escholarship.org/uc/item/8r3126tq The low-energy electric dipole response in the axially deformed 154Sm nucleus was investigated for the first time using complementary probes. The isoscalar (IS) response was extracted from an (α, α′γ) coincidence experiment and the isovector (IV) response from polarization observables measured with the ( p → , p → ′ ) reaction at 0∘. Both the IS and IV responses exhibit a resonance-like structure at excitation energies 5.5-6 MeV identified as the pygmy dipole resonance. Its evolution with deformation is investigated by comparison to the spherical isotope 144Sm. The low-energy IV strength in 154Sm departs from the K-splitting picture that characterizes the IV giant dipole resonance in this nucleus. This finding is further supported by the absence of significant IS strength above 7 MeV. https://escholarship.org/uc/item/8r3126tq Wed, 6 May 2026 00:00:00 +0000 Pellegri, L Jivan, H Krugmann, A Von Neumann-Cosel, P Pietralla, N Tamii, A Adsley, P Aoi, N Bahini, A Bertulani, CA Brummer, JW Coman, A Donaldson, LM Färber, M Fujita, H Fujita, Y Görgen, A Hashimoto, T Hatanaka, K Jones, PM Jongile, S Kawabata, T Khumalo, TC Lee, JHC Li, KCW Maeda, Y Malatji, KL https://orcid.org/0000-0001-7810-3366 Marín-Lámbarri, DJ Mihai, C Miki, K Molema, PT Mukwevho, NJ Negret, A Neveling, R Ong, HJ Papka, P Pesudo, V Rebeiro, BM Richter, A Sakaguchi, H Savran, D Shima, T Shimbara, Y Sideras-Haddad, E Siem, S Smit, FD Steyn, GF Suzuki, T Triambak, S Usman, IT Van Zyl, JJ Weinert, M Wiedeking, M https://orcid.org/0000-0003-4983-3882 Zenihiro, J https://escholarship.org/uc/item/7fb9069z Probing the j dependence of angular distributions and N = 20 shell rigidity via the 36 S( p , d ) 35 S reaction https://escholarship.org/uc/item/7fb9069z Wed, 6 May 2026 00:00:00 +0000 Anonymous https://escholarship.org/uc/item/5850m6j7 Vibrations from experimental setups and the environment are a persistent source of noise for low-temperature calorimeters searching for rare events, including neutrinoless double beta (0νββ) decay or dark matter interactions.

Brute-force calculation of the optimal set of included channels is exponentially infeasible as the number of channels grows, and approximate methods are required. In this work, we present a data-driven framework for attempting to find near-optimal sets of included detector channels. The framework leverages non-negative matrix factorization (NMF) to learn the behavior of gamma spectra across the detector and clusters similarly-performing detector channels together. Performance comparisons are then made between spectra with channel clusters removed, which is more feasible than brute force.

We demonstrate that finding and then subtracting point sources, finding and then subtracting models of clusters, and using a profile bias-hardened lensing estimator together reduce the fractional biases to well below statistical uncertainties, with the inferred lensing amplitude, A lens, biased by less than 0.2σ. We also show that another method where a model for the cosmic infrared background (CIB) contribution is deprojected and high-frequency data from Planck is included has similar performance. Other frequency-cleaned options do not perform as well, either incurring a large noise cost or resulting in biased recovery of the lensing spectrum.

Each of these surveys individually provides lensing measurements with similarly high statistical power, achieving signal-to-noise ratios of approximately 40. The combined lensing band powers represent the most precise CMB lensing power spectrum measurement to date with a signal-to-noise ratio of 61 and an amplitude of A_{lens}^{recon}=1.025±0.017 with respect to the theory prediction from the best-fit CMB Planck-ACT cosmology. The band powers from all three lensing datasets, analyzed jointly, yield a 1.6% measurement of the parameter combination S_{8}^{CMBL}≡σ_{8}(Ω_{m}/0.3)^{0.25}=0.825_{-0.013}^{+0.015}.

The photon requirement reduces the multijet background, and the H → b b ¯ decay is the dominant decay mode. Event selection requirements target events produced by vector-boson fusion, the dominant production mode in this channel. Several improvements enhance the search sensitivity compared to previous measurements. These improvements include better background modelling and characterization, the use of a neural-network classifier, and an updated signal extraction strategy adopting a direct binned-likelihood fit to the classifier output. With these improvements, the Higgs boson signal strength is measured to be 0.2 ± 0.7 relative to the Standard Model prediction.

When analyzing these data with extended cosmologies this inconsistency manifests as a ≃3σ preference for subminimal neutrino mass or evolving dark energy. It is known that the preference for subminimal neutrino mass from the suppression of structure growth could be alleviated by increasing the optical depth to reionization τ. We show that, because the CMB-inferred τ is negatively correlated with the matter fraction, a larger optical depth resolves a similar preference from geometric constraints. Optical depths large enough to resolve the neutrino mass tension (τ∼0.09) reduce the preference for evolving dark energy from ≃3σ to ≃1.5σ and increase the CMB-inferred values of ns and H0 to 0.968±0.004 and 67.94±0.44 km/s/Mpc, respectively.

Current astronomical data provide an upper limit on between 0.07–0.12 eV at 95% confidence, depending on the choice of data. This bound assumes that the cosmological model is Cold Dark Matter ( ), where dark energy is a cosmological constant, the spatial geometry is flat, and the primordial fluctuations follow a pure power law.

In this work, we show that the gas is more extended than the dark matter, and the amount of baryonic feedback at z≲1 disfavors low-feedback models such as that of state-of-the-art hydrodynamical simulation IllustrisTNG compared with high-feedback models such as that of the original Illustris simulation. This has important implications for bridging the gap between theory and observations and understanding galaxy formation and evolution. Furthermore, a better grasp of the baryon-dark matter link is critical to future cosmological analyses, which are currently impeded by our limited knowledge of baryonic feedback.

This can be very beneficial from several points of view, including, but not limited to, a reduction of the requirements for conventional substrate heating, the possibility to deposit films on temperature-sensitive substrates, the formation of metastable or otherwise unattainable phases, and the combination of deposition and etching effects. Non-equilibrium heating implies transient (sub-picosecond to picoseconds) and highly localized (nanometer-squared) events associated with the arrival of energetic particles from the plasma. These particles carry kinetic and potential energies to the substrate or film surface. While conventional heating drives the system always toward equilibrium, non-equilibrium heating events involve competing effects of defect generation (affected by momentum transfer) and annealing (by localized heating).... https://escholarship.org/uc/item/3fh1j9gv Sun, 26 Apr 2026 00:00:00 +0000 Anders, André https://orcid.org/0000-0002-5313-6505 https://escholarship.org/uc/item/24p4q664 This work provides a quantitative analysis of what it would take to fully evaporate copper macroparticles embedded in a cathodic arc plasma flow. This analysis is important for the justification of efforts to develop an evaporation scheme based on adding an electron beam. We want to explore if this approach could be an alternative to conventional plasma filtering to obtain macroparticle-free plasma from a cathodic arc plasma source. If successful, cathodic arc plasma deposition could be extended from a popular technology for hard and decorative coatings to much more demanding coatings applications, for example in microelectronics. Here, we study the feasibility and economical implication of evaporating micrometer-sized macroparticles on length and time scales typical for cathodic arc deposition systems.

In this regime, we present for the first time a complete calculation of the real NLO corrections, associated with gluon emissions outside the jet cones, at leading power in 1/P⊥. Our result exhibits TMD factorisation, with the same hard factor as at tree-level and a NLO correction to the Weiszäcker-Williams (WW) gluon transverse momentum dependent (TMD) distribution which involves four Wilson-line operators.

A new method of extracting lifetimes from experimental data, taking into account the unknown β-delayed neutron emission branches of very neutron-rich nuclei, was developed to enable systematic uncertainty analysis. The experiment observed a dramatic change in the half-life systematics for the isotopes with neutron number N=34. Beyond N=34, the decline of nuclear lifetime is much slower, leading to longer than anticipated lifetimes for near-dripline nuclei. State-of-the-art shell-model calculations can explain the experimental results, revealing the imprint of shell effects and the need for modification of single-particle neutron states.

While other methods of producing hydroxyl radicals are available, one benefit of using high flux density sources is that hydroxyl radical scavenging reactions can be minimized, and exposure times kept short to minimize secondary reactions. Here we present an application of the XFMS method using low dose rate X-rays from a commercial instrument. We demonstrate the feasibility of the approach using short peptides, characterizing the oxidative modifications +14, +16, and +32 Da under both aerobic and low oxygen conditions, and we additionally quantify the hydrogen peroxide production for various doses using the low dose rate source.

The charged current interaction proceeds through ^{13}C+ν_{e}→^{13}N+e^{-} which is followed, with a 10 minute half life, by ^{13}N→^{13}C+e^{+}+ν_{e}. The detection strategy is based on the delayed coincidence between the electron and the positron. Evidence for the charged current signal is presented with a significance of 4.2σ. Using the natural abundance of ^{13}C present in the scintillator, 5.7 metric tons of ^{13}C over 231 days of data were used in this analysis. The 5.6_{-2.3}^{+3.0} observed events in the data set are consistent with the expectation of 4.7_{-1.3}^{+0.6} events. This result is the second real-time measurement of CC interactions of ^{8}B neutrinos with nuclei and constitutes the lowest energy observation of neutrino interactions on ^{13}C generally. This enables the first direct measurement of the CC ν_{e} reaction to the ground state... https://escholarship.org/uc/item/7wn6x62g Thu, 23 Apr 2026 00:00:00 +0000 Abreu, M Allega, A Anderson, MR Andringa, S Asner, DM Auty, DJ Bacon, A Baltazar, T Barão, F Barros, N Bayes, R Beier, EW Bialek, A Biller, SD Caden, E Chen, M Cheng, S Cleveland, B Cookman, D https://orcid.org/0000-0001-9385-1194 Corning, J DeGraw, S Dehghani, R Deloye, J Depatie, MM Di Lodovico, F Dima, C Dittmer, J Dixon, KH Esmaeilian, MS Falk, E Fatemighomi, N Ford, R Gadamsetty, S Gaur, A González-Reina, OI Gooding, D Grant, C Grove, J Hall, S Hallin, AL Hallman, D Hebert, MR Heintzelman, WJ Helmer, RL Hewitt, C Hreljac, B Huang, P Hunt-Stokes, R Inácio, AS Jillings, CJ Kaluzienski, S Kaptanoglu, T Kladnik, J Klein, JR Kormos, LL Krar, B Kraus, C Krauss, CB Kroupová, T Lake, C Lebanowski, L https://orcid.org/0000-0002-8255-6613 Lefebvre, C Lozza, V Luo, M Maguire, S Maio, A Manecki, S Maneira, J Martin, RD McCauley, N McDonald, AB Milton, G Morris, D Mubasher, M Naugle, S Nolan, LJ O’Keeffe, HM Gann, GD Orebi Ouyang, S Page, J Pal, S Paleshi, K Parker, W Pickard, LJ Quenallata, B Ravi, P Reichold, A Riccetto, S Rose, J Rosero, R Shen, J Simms, J Skensved, P Smiley, M Tafirout, R Tam, B Tseng, J Vázquez-Jáuregui, E Virtue, CJ Wang, F https://escholarship.org/uc/item/78c566x5 Accurate measurement of the cosmogenic muon-induced neutron yield is crucial for constraining a significant background in a wide range of low-energy physics searches. Although previous underground experiments have measured this yield across various cosmogenic muon energies, is uniquely positioned due to its exposure to one of the highest average cosmogenic muon energies at 364 GeV. Using ultrapure water, we have determined a neutron yield of at . Comparison with simulations demonstrates clear agreement with the neutron production model, highlighting discrepancies with the widely used 4 model. Furthermore, this measurement reveals a lower cosmogenic neutron yield than that observed by the SNO experiment, which used heavy water under identical muon flux conditions. This result provides new evidence that nuclear structure and target material composition significantly influence neutron production by cosmogenic muons, offering fresh insight with important implications for the... https://escholarship.org/uc/item/78c566x5 Thu, 23 Apr 2026 00:00:00 +0000 Abreu, M Allega, A Anderson, MR Andringa, S Asner, DM Auty, DJ Bacon, A Baltazar, T Barão, F Barros, N Bayes, R Beier, EW Bialek, A Biller, SD Caden, E Callaghan, EJ Chen, M Cheng, S Cleveland, B Cookman, D https://orcid.org/0000-0001-9385-1194 Corning, J DeGraw, S Dehghani, R Deloye, J Depatie, MM Dima, C Dittmer, J Dixon, KH Esmaeilian, MS Falk, E Fatemighomi, N Ford, R Gadamsetty, S Gaur, A Gooding, D Grant, C Grove, J Hall, S Hallin, AL Hallman, D Hebert, MR Heintzelman, WJ Helmer, RL Hewitt, C Hreljac, B Huang, P Hunt-Stokes, R Inácio, AS Jillings, CJ Kaluzienski, S Kaptanoglu, T Kladnik, J Klein, JR Kormos, LL Krar, B Kraus, C Kroupová, T Lake, C Lebanowski, L https://orcid.org/0000-0002-8255-6613 Lefebvre, C Liggins, B Lozza, V Luo, M Maguire, S Maio, A Manecki, S Maneira, J Martin, RD McCauley, N McDonald, AB Milton, G Morris, D Mubasher, M Naugle, S Nolan, LJ O’Keeffe, HM Gann, GD Orebi Ouyang, S Page, J Pal, S Paleshi, K Parker, W Pickard, LJ Pitelka, RC Quenallata, B Ravi, P Reichold, A Riccetto, S Rose, J Rosero, R Shen, J Simms, J Skensved, P Smiley, M Stringer, MI Tafirout, R Tam, B Tseng, J Vázquez-Jáuregui, E Virtue, CJ https://escholarship.org/uc/item/5vx384hq Bi-2212 Rutherford cables have been fabricated into flat racetrack coils and canted-cosine-theta dipole magnets. The performance gap between the magnets made with Rutherford cables and the short-sample-limit is about 30. To better understand the influence of Rutherford cable processing on the strand performance, we studied three Bi-2212 wires with filament architectures of 37 18 and 55 18 and diameters of 0.8 and 1.0 mm. To simulate the deformation caused by cabling process, the three wires were rolled with thickness reductions ranging from 10 to 30. The aspect ratios of rolled strands are between 1.29 and 2.05. The low aspect-ratio wire is also an interesting form for fabricating solenoid coils with higher packing density. The round and rolled strands were heat-treated under 50 bar and with maximum heat treatment temperatures of 885.5 C and 890.5 C. The rolling deformation reduced filament size uniformity, resulting in filament merging in fully heat-treated wires. It was found... https://escholarship.org/uc/item/5vx384hq Thu, 23 Apr 2026 00:00:00 +0000 Jiang, Jianyi Kvitkovic, Jozef Linville, Caitlynn Brown, Jamia Jones, Jakeyvan Davis, Daniel S Kim, Youngjae Kametani, Fumitake Trociewitz, Ulf P Hellstrom, Eric E Larbalestier, David C Croteau, Jean-Francois https://orcid.org/0000-0002-3486-8401 Escobar, Christopher Shen, Tengming https://escholarship.org/uc/item/4xb45973 The SNO+ experiment is located 2 km underground at SNOLAB in Sudbury, Canada. A low background search for neutrinoless double beta (0νββ) decay will be conducted using 780 tonnes of liquid scintillator loaded with 3.9 tonnes of natural tellurium, corresponding to 1.3 tonnes of 130Te. This paper provides a general overview of the SNO+ experiment, including detector design, construction of process plants, commissioning efforts, electronics upgrades, data acquisition systems, and calibration techniques. The SNO+ collaboration is reusing the acrylic vessel, PMT array, and electronics of the SNO detector, having made a number of experimental upgrades and essential adaptations for use with the liquid scintillator. With low backgrounds and a low energy threshold, the SNO+ collaboration will also pursue a rich physics program beyond the search for 0νββ decay, including studies of geo- and reactor antineutrinos, supernova and solar neutrinos, and exotic physics such as the search for invisible... https://escholarship.org/uc/item/4xb45973 Thu, 23 Apr 2026 00:00:00 +0000 Albanese, V Alves, R Anderson, MR Andringa, S Anselmo, L Arushanova, E Asahi, S Askins, M Auty, DJ Back, AR Back, S Barão, F Barnard, Z Barr, A Barros, N Bartlett, D Bayes, R Beaudoin, C Beier, EW Berardi, G Bialek, A Biller, SD Blucher, E Bonventre, R Boulay, M Braid, D Caden, E Callaghan, EJ Caravaca, J Carvalho, J Cavalli, L Chauhan, D Chen, M Chkvorets, O Clark, KJ Cleveland, B Connors, C Cookman, D https://orcid.org/0000-0001-9385-1194 Coulter, IT Cox, MA Cressy, D Dai, X Darrach, C Davis-Purcell, B Deluce, C Depatie, MM Descamps, F Di Lodovico, F Dittmer, J Doxtator, A Duhaime, N Duncan, F Dunger, J Earle, AD Fabris, D Falk, E Farrugia, A Fatemighomi, N Felber, C Fischer, V Fletcher, E Ford, R Frankiewicz, K Gagnon, N Gaur, A Gauthier, J Gibson-Foster, A Gilje, K González-Reina, OI Gooding, D Gorel, P Graham, K Grant, C Grove, J Grullon, S Guillian, E Hall, S Hallin, AL Hallman, D Hans, S Hartnell, J Harvey, P Hedayatipour, M Heintzelman, WJ Heise, J Helmer, RL Hodak, B Hodak, M Hood, M Horne, D Hreljac, B Hu, J Hussain, SMA Iida, T Inácio, AS Jackson, CM Jelley, NA Jillings, CJ Jones, C Jones, PG https://escholarship.org/uc/item/3x6706z6 We present a novel multimessenger approach to extract the effective radial flow of the quark-gluon plasma (QGP) by jointly analyzing thermal photon and dilepton spectra in heavy-ion collisions. A key feature of this method is that it circumvents the need for a directly unmeasurable reference-the photon temperature in the absence of flow-by establishing, within a calibrated model framework, a stable, approximately linear correlation with the dilepton-inferred temperature. This construction defines an experimentally constructible quantity, v_{r}^{eff}, which reflects early-time collectivity and exhibits a strong correlation with the spacetime-averaged radial velocity of the QGP. Together with previous results linking dilepton slopes to the initial QGP temperature, our work establishes a consistent framework for electromagnetic tomography of the QGP. Our framework quantifies the experimental precision target, thereby providing a concrete road map for future measurements at RHIC and... https://escholarship.org/uc/item/3x6706z6 Thu, 23 Apr 2026 00:00:00 +0000 Du, Lipei https://orcid.org/0000-0002-3029-6602 Heinz, Ulrich https://escholarship.org/uc/item/2jt500hd We present a 9.3σ detection of the pairwise kinematic Sunyaev-Zel’dovich (kSZ) effect by combining a sample of 913,286 Luminous Red Galaxies (LRGs) from the Dark Energy Spectroscopic Instrument Data Release 1 (DESI DR1) catalog and coadded Atacama Cosmology Telescope (ACT DR6) and Planck cosmic microwave background (CMB) temperature maps. This represents the highest-significance pairwise kSZ measurement to date. The analysis uses three ACT CMB temperature maps: coadded 150 GHz, total frequency maps, and a component separated Internal Linear Combination (ILC) map, all of which cover 19,000 square degrees of the sky from Advanced ACTPol observations conducted between 2017 and 2022. Comparison of the results of these three maps serves as a consistency check for potential foreground contamination that may depend on the observation frequency. An estimate of the best-fit mass-averaged optical depth is obtained by comparing the pairwise kSZ curve with the linear theory prediction of... https://escholarship.org/uc/item/2jt500hd Thu, 23 Apr 2026 00:00:00 +0000 Gong, Yulin Gallardo, Patricio A Bean, Rachel Moore, Jenna Vavagiakis, Eve M Battaglia, Nicholas Hadzhiyska, Boryana Hsu, Yun-Hsin Aguilar, Jessica Nicole Ahlen, Steven Bianchi, Davide Brooks, David Claybaugh, Todd Canning, Rebecca Devlin, Mark Doel, Peter de la Macorra, Axel Ferraro, Simone Font-Ribera, Andreu Forero-Romero, Jaime E Gaztañaga, Enrique Gutierrez, Gaston Gontcho, Satya Gontcho A Guy, Julien https://orcid.org/0000-0001-9822-6793 Honscheid, Klaus Howlett, Cullan Liu, R Henry Ishak, Mustapha Joyce, Dick Kremin, Anthony https://orcid.org/0000-0003-0667-5941 Lamman, Claire Levi, Michael Landriau, Martin Manera, Marc Meisner, Aaron Miquel, Ramon Niemack, Michael D Nadathur, Seshadri Percival, Will Prada, Francisco Rossi, Graziano Guachalla, Bernardita Ried Sanchez, Eusebio Seo, Hee-Jong Sprayberry, David Schlegel, David Sifón, Cristóbal Schubnell, Michael Silber, Joseph Harry https://orcid.org/0000-0002-3461-0320 Tarlé, Gregory Weaver, Benjamin Alan Zhou, Rongpu Zou, Hu
