The 4H-SiC LGADs exhibit fast signal responses, and a time resolution of 61 ps was achieved, comparable to that of standard Si LGADs. The present limitation in the time resolution of 4H-SiC LGADs appears to stem from limited charge generation. Nevertheless, their higher voltage tolerance and faster carrier drift suggest that, with increased charge collection, their timing performance could approach or even surpass that of Si LGADs. These results demonstrate the strong potential of 4H-SiC LGADs as a robust platform for precision timing in future 4-D tracking detectors, while also highlighting that signal charge is the dominant factor currently limiting their performance, indicating that further optimization of gain and drift structures will be essential for future development. https://escholarship.org/uc/item/7q14g34g Fri, 21 Aug 2026 00:00:00 +0000 Yang, Tao https://orcid.org/0000-0003-2161-5808 Satapathy, Yashas Sekely, Ben J Tishelman-Charny, Abraham Allion, Greg Atar, Gil Barletta, Philip Haber, Carl Holland, Steve Muth, John F Pavlidis, Spyridon Stucci, Stefania https://escholarship.org/uc/item/6d52d95v In the heterodyne approach to axion detection, axion dark matter induces transitions between two modes of a microwave cavity, resulting in a parametrically enhanced signal power. We describe the fabrication and characterization of a prototype normal conducting cavity specifically optimized for heterodyne detection. Corrugations on the cavity walls support linearly polarized hybrid modes which maximize the signal power while strongly suppressing noise. We demonstrate tuning mechanisms which allow one mode frequency to be scanned across a 4 MHz range, while suppressing cross-coupling noise by at least 80 dB. A future superconducting cavity with identical geometry to our prototype would have the potential to probe orders of magnitude beyond astrophysical bounds. https://escholarship.org/uc/item/6d52d95v Fri, 21 Aug 2026 00:00:00 +0000 Li, Zenghai Zhou, Kevin https://orcid.org/0000-0002-9810-3977 Oriunno, Marco Berlin, Asher Calatroni, Sergio D’Agnolo, Raffaele Tito Ellis, Sebastian AR Schuster, Philip Tantawi, Sami G Toro, Natalia https://escholarship.org/uc/item/7n99q295 Particle physics theories, such as those which explain neutrino flavor mixing, arise from a vast landscape of model-building possibilities. A model’s construction typically relies on the intuition of theorists. It also requires considerable effort to identify appropriate symmetry groups, assign field representations, and extract predictions for comparison with experimental data. We develop Autonomous Model Builder (AMBer), a framework in which a reinforcement learning agent interacts with a streamlined physics software pipeline to search these spaces efficiently. AMBer selects symmetry groups, particle content, and group representation assignments to construct models while minimizing the number of free parameters introduced. We validate our approach in well-studied regions of theory space and extend the exploration to a previously unexamined symmetry group. While demonstrated in the context of neutrino flavor theories, this approach of reinforcement learning with physics software... https://escholarship.org/uc/item/7n99q295 Thu, 20 Aug 2026 00:00:00 +0000 Baretz, Jason Benjamin Fieg, Max Ganesh, Vijay Ghosh, Aishik https://orcid.org/0000-0003-0819-1553 Knapp-Pérez, V Rudolph, Jake Whiteson, Daniel https://orcid.org/0000-0002-2005-3113 https://escholarship.org/uc/item/3pz3r1sh A measurement of the associated production of a top-quark pair with the Higgs boson (tt¯H$$ t\overline{t}H $$) in multilepton final states is presented. The analysis is based on a data sample of proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV recorded with the ATLAS detector at the CERN Large Hadron Collider and corresponding to an integrated luminosity of 140 fb−1. Six final states defined by the number and flavour of reconstructed charged leptons are combined in a simultaneous likelihood fit to extract the tt¯H$$ t\overline{t}H $$ signal and constrain the most relevant backgrounds. The measured tt¯H$$ t\overline{t}H $$ cross-section normalised to Standard Model (SM) prediction is σtt¯H/σSM=0.63−0.19+0.20$$ {\sigma}_{t\overline{t}H}/{\sigma}^{\mathrm{SM}}=0.{63}_{-0.19}^{+0.20} $$. This result corresponds to an observed (expected) significance of 3.3σ (5.3σ).

Events are required to feature an energetic jet, large missing transverse momentum, and at least one low-momentum charged particle that serves as a candidate higgsino decay product. In the first search, targeting higgsino mass splittings in the range of 0.3–1 GeV, the higgsinos are expected to predominantly decay into pions that are identified as low-momentum charged particles with large transverse impact parameters due to the long higgsino lifetime (cτ ≈ ?(0.1–10 mm)), and neural networks are used to discriminate between signal and background processes. The second search targets larger mass splittings in the range of 1–3 GeV, where the higgsinos are expected to decay promptly into low-momentum leptons, one of which is identified by dedicated... https://escholarship.org/uc/item/9474w7zh Wed, 19 Aug 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 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, JS Allen, JF Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y 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 https://escholarship.org/uc/item/9318f4d5 This Letter analyzes the sensitivity of event geometry estimators to the initial-state kinematics of hard scattering in proton–lead collisions. 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 . The jets are measured within the pseudorapidity interval −2.8  <  η  <  4.5, where positive η values correspond to the direction of the proton beam. Results are presented as a function of the Bjorken-x of the parton originating from the proton, xp .

The result is used to place constraints on exotic decays of the Higgs boson into four τ-leptons, H→aa→τ+τ−τ+τ−. This search focuses on events with either one or two τ-leptons decaying into hadrons and neutrinos, and the remaining three or two τ-leptons decaying into either electron or muon and neutrinos. No significant excess is observed above the expected Standard Model background and upper limits at the 95% confidence level on B(H→aa→τ+τ−τ+τ−) are set ranging from 0.06 to 0.23, depending on the mass ma ranging from 15 to 60 GeV. https://escholarship.org/uc/item/7mh4f656 Wed, 19 Aug 2026 00:00:00 +0000 Collaboration, The ATLAS https://escholarship.org/uc/item/5p3019t4 Skipper charge-coupled devices (CCDs) are ultralow-threshold detectors capable of detecting energy deposits in silicon at the electronvolt scale. Skipper CCDs are increasingly used in rare-event searches, including experiments such as SENSEI, DAMIC-M, Oscura, and CONNIE, where one of the major challenges is mitigating low-energy backgrounds. In this work, we present results on trap characterization in a silicon skipper-CCD produced in the same fabrication run as the SENSEI experiment at SNOLAB. Lattice defects contribute to backgrounds in rare-event searches through single-electron charge trapping. To investigate this, we use the charge-pumping technique at different temperatures to identify dipoles produced by traps in the CCD channel. We fully characterize a fraction of these traps and use this information to extrapolate their contribution to the single-electron background in SENSEI. We find that this subpopulation of traps does not contribute significantly, but more work is... https://escholarship.org/uc/item/5p3019t4 Wed, 19 Aug 2026 00:00:00 +0000 Brusco, Agustin Sivilotti, Bruno Botti, Ana M Cervantes, Brenda Desai, Ansh Essig, Rouven Estrada, Juan Etzion, Erez Moroni, Guillermo Fernandez Holland, Stephen E https://orcid.org/0000-0001-7218-3457 Lawson, Ian Luoma, Steffon Perez, Santiago E Rodrigues, Dario Tiffenberg, Javier Uemura, Sho Wu, Yikai https://escholarship.org/uc/item/39r313rc We use supersymmetric chiral dynamics perturbed by anomaly-mediated supersymmetry breaking to obtain a high-quality, composite axion that solves the strong problem. The strong dynamics arises from a supersymmetric SU(10) chiral gauge theory with massless matter chiral superfields. This leads to a stable, nonsupersymmetric vacuum, calculated exactly, where a spontaneously broken global symmetry, identified with the Peccei-Quinn (PQ) symmetry, gives rise to a composite QCD axion. The chiral gauge theory also admits a discrete (or ) gauge symmetry that forbids PQ-violating operators up to dimension eight. An extension to an chiral gauge theory incorporates grand unification where the unification scale is identified with the PQ-breaking scale and PQ-violating operators are forbidden up to dimension 20. The supersymmetry breaking scale, near 100 TeV, ameliorates the Higgs hierarchy problem, while colored Nambu–Goldstone bosons may be detected at future colliders via decays... https://escholarship.org/uc/item/39r313rc Wed, 19 Aug 2026 00:00:00 +0000 Gherghetta, Tony Murayama, Hitoshi Noether, Bea Quílez, Pablo https://escholarship.org/uc/item/9b3494xv The Galactic Center Excess (GCE) may yet herald the discovery of annihilating dark matter. Weighing against that conclusion are analyses showing evidence for dim point sources within the spatial structure of the emission. Because of technical limitations these analyses are purely spatial with all spectral information that could disentangle the excess from astrophysical backgrounds discarded. Here, we demonstrate that a neural network simulation-based inference approach can jointly analyze the spatial and spectra data. The addition is profound: energy information drives the putative point sources to be significantly dimmer, indicating either the GCE is truly diffuse in nature or made of an exceptionally large number of sources. Quantitatively, for our best fit background model, the excess is essentially consistent with Poisson emission as predicted by dark matter. If due to point sources, our median prediction is O(10^{5}) sources, or more than 35 000 at 90% confidence-both... https://escholarship.org/uc/item/9b3494xv Tue, 18 Aug 2026 00:00:00 +0000 List, Florian Park, Yujin Rodd, Nicholas L https://orcid.org/0000-0003-3472-7606 Schoen, Eve https://orcid.org/0000-0001-8360-2098 Wolf, Florian https://escholarship.org/uc/item/6b5328td Context. Understanding how galaxies trace the underlying matter density field is essential for characterizing the influence of the large-scale structure on galaxy formation, being therefore a key ingredient in observational cosmology. This connection, commonly described through the galaxy bias, b , can be studied effectively using machine-learning (ML) techniques, which offer strong predictive capabilities and can capture nonlinear relationships in high-dimensional data. Recent work has also highlighted the need for probabilistic methods to properly account for the intrinsic stochasticity of this connection. Aims. We aim to incorporate the linear bias parameter assigned to individual galaxies into a ML framework, quantify its dependence on various halo and environmental properties, and evaluate whether different algorithms can accurately predict this parameter and reproduce the scatter in several bias relations.

The analysis uses proton-proton collision data corresponding to an integrated luminosity of 140 fb−1, recorded by the ATLAS detector at the Large Hadron Collider between 2015 and 2018. The search targets hypothetical dimuon resonances in the invariant mass range from 35 GeV to 75 GeV. The modelling of this mass region is particularly challenging for conventional analytic background parameterisations. To address this, a Gaussian process regression technique is used to model the background. The dimuon mass spectrum is analysed for potential signals, and no statistically significant excess is observed. Upper limits at the 95% confidence level are set on the fiducial production cross-section of new resonances decaying promptly into muons, ranging from 20 fb to 110 fb, depending on the resonance mass. These results are further interpreted in the context of dark-photon and... https://escholarship.org/uc/item/63667427 Tue, 18 Aug 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 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 Åkesson, TPA 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 Allaire, C Allbrooke, BMM Allen, DR Allen, JS Allen, JF Alley, CS Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y Ambler, A Amelung, C Amerl, M Amezza, T Amini, B Amirie, K Amirkhanov, A Amor Dos Santos, SP 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 Aparo, MA Aperio Bella, L Apicella, M Appelt, C https://escholarship.org/uc/item/4r4159cj Semianalytic models are a widely used approach to simulate galaxy properties within a cosmological framework, relying on simplified yet physically motivated prescriptions. They have also proven to be an efficient alternative for generating accurate galaxy catalogs, offering a faster and less computationally expensive option compared to full hydrodynamical simulations. In this paper, we demonstrate that, using only galaxy 3D positions and radial velocities, we can train a graph neural network coupled to a moment neural network to obtain a robust machine-learning-based model capable of estimating the matter density parameters, Ωm, with a precision of approximately 10%. The network is trained on (25 h−1 Mpc)3 volumes of galaxy catalogs from L-Galaxies and can successfully extrapolate its predictions to other semianalytic models (GAEA, SC-SAM, and Shark) and, more remarkably, to hydrodynamical simulations (Astrid, SIMBA, IllustrisTNG, and SWIFT-EAGLE).

With increasingly sensitive instruments being deployed, secondary -modes induced by the weak gravitational lensing of CMB photons are becoming an important limitation and need to be removed, a process known as delensing. In this work, we combine internally reconstructed CMB lensing maps from the Atacama Cosmology Telescope (ACT) data release 6 (DR6) with galaxy samples from unWISE and a map of the cosmic infrared background (CIB) fluctuations from Planck to produce a well-correlated tracer of the CMB lensing field. Our coadded tracer, shown to be 55%–85% correlated with the true lensing convergence at multipoles , is then convolved with ACT DR6 -mode polarization to yield a template of the lensing -modes. We assess its performance on a wide range of scales by using it to delens ACT DR6 and Planck -modes... https://escholarship.org/uc/item/3cr9t6sn Tue, 18 Aug 2026 00:00:00 +0000 Hertig, Emilie Lizancos, Antón Baleato Qu, Frank J Bond, J Richard Calabrese, Erminia Challinor, Anthony Devlin, Mark J Dunkley, Jo Louis, Thibaut Madhavacheril, Mathew S Namikawa, Toshiya Page, Lyman A Sehgal, Neelima Sherwin, Blake Sifón, Cristóbal Staggs, Suzanne T Wollack, Edward J https://escholarship.org/uc/item/2wc0r6kp We present the first constraints on multipole-dependent cosmic birefringence using CMB polarization data from the BK18 dataset, which combines observations from BICEP2, Array, and BICEP3 at frequencies of 95, 150, and 220 GHz. Photon coupling to an axionlike field leads to the rotation of CMB polarization, inducing nonzero cross-correlations. We show that a multipole-dependent rotation imprints a distinct signature in the polarization spectra that can be constrained. Specifically, we consider an early dark energy (EDE) scenario in which a pseudoscalar field couples to photons through a Chern-Simons interaction, generating a polarization rotation with multipole dependence. We introduce a phenomenological as a step function, obtaining constraints on the step function size consistent with zero, with uncertainties less than (68% CL). In addition, using multi-frequency , , and cross spectra, along with robust BICEP/ foreground treatment and likelihood framework, we... https://escholarship.org/uc/item/2wc0r6kp Tue, 18 Aug 2026 00:00:00 +0000 Ade, PAR Ahmed, Z Amiri, M Barkats, D Thakur, R Basu Bischoff, CA Beck, D Bock, JJ Boenish, H Buza, V Cantrall, B Cheshire, JR Connors, J Cornelison, J Crumrine, M Cukierman, AJ Denison, E Duband, L Echter, M Eiben, M Elwood, BD Fatigoni, S Filippini, JP Fortes, A Gao, M Giannakopoulos, C Goeckner-Wald, N Goldfinger, DC Gratton, S Grayson, JA Greathouse, A Grimes, PK Hall, G Halal, G Halpern, M Hand, E Harrison, SA Henderson, S Hoang, TD Hubmayr, J Hui, H Irwin, KD Kang, JH Karkare, KS Kefeli, S Kovac, JM Kuo, C Lasko, K Lau, K Lautzenhiser, M Lennox, A Liu, T Mackey, SC Maher, N Megerian, KG Minutolo, L Moncelsi, L Nakato, Y Nguyen, HT O’Brient, R Paine, SN Patel, A Petroff, MA Polish, AR Prouve, T Pryke, C Reintsema, CD Richter, S Romand, T Salatino, M Schillaci, A Schmitt, B Schwartz, R Sheehy, CD Singari, B Soliman, A St. Germaine, T Steiger, A Steinbach, B Sudiwala, R Teply, G Thompson, KL Tucker, C Turner, AD Vergès, C Vieregg, AG Wandui, A Weber, AC Willmert, J Wong, CL Wu, WLK Yang, H Yu, C Zheng, L Zhang, C Zhang, S https://escholarship.org/uc/item/1k95s9bg Aims. This paper has two aims: the first aim is to build a large homogeneous spectrophotometric sample of Type Ia supernovae (SNe Ia) from the second data release of the Zwicky Transient Facility (ZTF DR2). We used the spectrum sample from the low-resolution ( R ∼ 100) SEDmachine (SEDm) Integral Field Spectrograph (IFS) that gathered 3069 spectra. This is one of the largest samples of such collections that can attempt to reproduce the Twins Embedding (TE) spectrophotometric standardization method. This is our second objective. The method was developed based on high-quality spectra from 200 SNe Ia of the Nearby Supernova factory (SNfactory) and led to an exceptionally low value of 0.073 mag for the intrinsic scatter. Methods. As the SEDm is not designed as a spectrophotometric instrument, we first improved the flux-calibration accuracy of the SN Ia spectrum sample using the ZTF photometric data, which were calibrated at the percent level. We corrected the spectra for second-order... https://escholarship.org/uc/item/1k95s9bg Tue, 18 Aug 2026 00:00:00 +0000 Ganot, C Copin, Y Rigault, M Dimitriadis, G Goobar, A Maguire, K Nordin, J Smith, M Aldering, G Barjou-Delayre, C Betoule, M Bloom, JS Burgaz, U Galbany, L Ginolin, M Graham, M Hale, D Johansson, J Kasliwal, MM Kim, Y-L Masci, FJ Müller-Bravo, TE Perlmutter, S https://orcid.org/0000-0002-4436-4661 Popovic, B Purdum, JN Rusholme, B Sollerman, J Terwel, JH Townsend, A https://escholarship.org/uc/item/1400q724 A search for resonant structures in the mass spectrum is performed using proton-proton collision data at , corresponding to an integrated luminosity of , recorded by the ATLAS experiment at the LHC.

Simulations suggest that neutron star mergers may produce magnetic fields as strong as 1017 G, but computational difficulties have hampered the inclusion of magnetic field effects in neutrino interaction rates. In this paper we give approximate interaction rates for neutrinos in the presence of strong magnetic fields, including the effects of Landau quantization and anomalous magnetic moments with errors of order T/M. We also comment on a neutrino production channel from individual neutrons that can produce low-energy νν¯ pairs of all three flavors even at low density. https://escholarship.org/uc/item/0t35g233 Sun, 9 Aug 2026 00:00:00 +0000 Kumamoto, Mia Welch, Catherine https://escholarship.org/uc/item/9x73w5pk The Data Release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI) is the largest sample to date for small-scale Lyα forest cosmology, accessed through its one-dimensional power spectrum (P 1D). The Lyα forest P 1D is extracted from quasar spectra that are highly inhomogeneous (both in wavelength and between quasars) in noise properties due to intrinsic properties of the quasar, atmospheric and astrophysical contamination, and also sensitive to low-level details of the spectral extraction pipeline. We employ two estimators in DR1 analysis to measure P 1D: the optimal estimator and the fast Fourier transform (FFT) estimator. To ensure robustness of our DR1 measurements, we validate these two power spectrum and covariance matrix estimation methodologies against the challenging aspects of the data. First, using a set of 20 synthetic 1D realizations of DR1, we derive the masking bias corrections needed for the FFT estimator and the continuum fitting bias needed for both estimators.... https://escholarship.org/uc/item/9x73w5pk Tue, 4 Aug 2026 00:00:00 +0000 Karaçaylı, Naim Göksel Ravoux, Corentin Martini, Paul Le Goff, Jean-Marc Armengaud, Eric Abdul-Karim, M Aguilar, J Ahlen, S Anand, A https://orcid.org/0000-0003-2923-1585 BenZvi, S Bianchi, D Brooks, D Claybaugh, T Cuceu, A https://orcid.org/0000-0002-2169-0595 de la Macorra, A Dey, Biprateep Doel, P Ferraro, S https://orcid.org/0000-0003-4992-7854 Font-Ribera, A Forero-Romero, JE Gaztañaga, E Gontcho, S Gontcho A Gutierrez, G Herrera-Alcantar, HK Honscheid, K Ishak, M Jimenez, J Joyce, R Kirkby, D https://orcid.org/0000-0002-8828-5463 Kisner, T Kremin, A https://orcid.org/0000-0001-6356-7424 Lahav, O Landriau, M https://orcid.org/0000-0003-1838-8528 Le Guillou, L Manera, M Meisner, A Miquel, R Nadathur, S Niz, G Palanque-Delabrouille, N Percival, WJ Poppett, C Prada, F Pérez-Ràfols, I Rossi, G Sanchez, E Schlegel, D Schubnell, M Seo, H Silber, J https://orcid.org/0000-0002-3461-0320 Sprayberry, D Tan, T Tarlé, G Walther, M Weaver, BA Zou, H https://escholarship.org/uc/item/98p9j514 The effective redshift distribution n(z) of galaxies is a critical component in the study of weak gravitational lensing. Here, we introduce a new method for determining n(z) for weak lensing surveys based on high-quality redshifts and neural-network-based importance weights. Additionally, we present the first unified photometric redshift calibration of the three leading stage-III weak lensing surveys, the Dark Energy Survey (DES), the Hyper Suprime-Cam (HSC) survey, and the Kilo-Degree Survey (KiDS), with state-of-the-art spectroscopic data from the Dark Energy Spectroscopic Instrument (DESI). We verify our method using a new, data-driven approach and obtain n(z) constraints with statistical uncertainties of the order of σz¯∼0.01 and smaller. Our analysis is largely independent of previous photometric redshift calibrations and, thus, provides an important cross-check in light of recent cosmological tensions. Overall, we find excellent agreement with previously published results... https://escholarship.org/uc/item/98p9j514 Tue, 4 Aug 2026 00:00:00 +0000 Lange, JU Blanco, D Leauthaud, A Wright, AH Fisher, A Ratajczak, J Aguilar, J Ahlen, S Bailey, S https://orcid.org/0000-0003-4162-6619 Bianchi, D Blake, C Brooks, D Claybaugh, T Cuceu, A https://orcid.org/0000-0002-2169-0595 Dawson, KS de la Macorra, A DeRose, J Dey, Arjun Doel, P Emas, N Ferraro, S https://orcid.org/0000-0003-4992-7854 Font-Ribera, A Forero-Romero, JE Garcia-Quintero, C Gaztañaga, E Gontcho, S Gontcho A Gutierrez, G Heydenreich, S Hildebrandt, H Ishak, M Jimenez, J Joudaki, S Kehoe, R Kirkby, D https://orcid.org/0000-0002-8828-5463 Kisner, T Kremin, A https://orcid.org/0000-0001-6356-7424 Lahav, O Lamman, C Landriau, M https://orcid.org/0000-0003-1838-8528 Le Guillou, L Levi, ME https://orcid.org/0000-0003-1887-1018 Medina-Varela, L Meisner, A Miquel, R Moustakas, J Nadathur, S Newman, JA Palanque-Delabrouille, N Porredon, A Prada, F Pérez-Ràfols, I Rossi, G Ruggeri, R Sanchez, E Saulder, C Schlegel, D https://orcid.org/0000-0002-5042-5088 Schubnell, M Sprayberry, D Sun, Z Tarlé, G Weaver, BA Yuan, S Zarrouk, P Zou, H https://escholarship.org/uc/item/90j6b8rn This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overlapping tracers (galaxies of distinct types) in the same redshift range.

DESI DR1 contains ∼ 30% of the final DESI LRG sample and less than 25% of the final ELG sample, and the combination of LRGs and ELGs increases the number density and reduces the shot noise.

Using the Luminous Red Galaxy sample from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2, we identify galaxy multiplets as discrete objects and measure their cross-correlations with the general galaxy field. Our results show that the multiplets exhibit stronger clustering bias as they trace more massive dark matter haloes than individual galaxies. When comparing the observed clustering statistics with the mock catalogues generated from the N-body simulation AbacusSummit, we find that the mocks underpredict multiplet clustering despite reproducing the galaxy two-point autocorrelation reasonably well. This discrepancy indicates that the standard Halo Occupation Distribution (HOD) model is insufficient to describe the properties of galaxy multiplets, revealing the greater constraining power of this higher order statistic on galaxy–halo... https://escholarship.org/uc/item/90j444fn Tue, 4 Aug 2026 00:00:00 +0000 Wang, Hanyue Eisenstein, Daniel J Aguilar, Jessica Nicole Ahlen, Steven Bianchi, Davide Brooks, David Claybaugh, Todd de la Macorra, Axel Dey, Arjun Dey, Biprateep Doel, Peter Ferraro, Simone Font-Ribera, Andreu Forero-Romero, Jaime E Gaztañaga, Enrique Gutierrez, Gaston Honscheid, Klaus Ishak, Mustapha Joyce, Richard Juneau, Stephanie Kirkby, David https://orcid.org/0000-0002-8828-5463 Kisner, Theodore Kremin, Anthony https://orcid.org/0000-0001-6356-7424 Lahav, Ofer Lamman, Claire Landriau, Martin Manera, Marc Meisner, Aaron Miquel, Ramon Mueller, Eva-Maria Nadathur, Seshadri Niz, Gustavo Palanque-Delabrouille, Nathalie Percival, Will J Prada, Francisco Pérez-Ràfols, Ignasi Ross, Ashley J Rossi, Graziano Sanchez, Eusebio Schlegel, David Schubnell, Michael Silber, Joseph Harry https://orcid.org/0000-0002-3461-0320 Sprayberry, David Tarlé, Gregory Weaver, Benjamin Alan Zhou, Rongpu https://orcid.org/0000-0001-5381-4372 Zou, Hu https://escholarship.org/uc/item/9075h84k The Milky Way Backup Program (MWBP), a survey currently underway with the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U.

We interpret the clustering of such samples using both Halo Occupation Distribution (HOD) modeling and a perturbation theory description of large-scale structure.

We present a sub-2% measurement of the Hubble constant that is independent of this scale, using data from the first data release of the Dark Energy Spectroscopic Instrument (DESI DR1). Building on previous work, we remove dependency on the sound horizon size using a heuristic rescaling procedure at the power spectrum level. A key innovation is the inclusion of uncalibrated (agnostic to rs ) post-reconstruction BAO measurements from DESI DR1, as well as using the CMB acoustic scale θ * as a high-redshift anchor. Uncalibrated type-Ia supernovae are often included as an independent source of Ωm information; here we demonstrate the robustness of our results by additionally considering two supernova-independent alternative datasets.

These strong lenses were found in the DESI Legacy Imaging Surveys using residual neural networks and followed up by our Hubble Space Telescope program, with all systems displaying unambiguous lensed arcs. With NIRES, we target eight lensed sources at redshifts difficult to measure in the optical range and determine the source redshifts for six, between zs = 1.675 and 3.332.

In this work, we present the first cosmological forecasts without continuum fitting distortion in the Lyα forest, focusing on the recovery of large-scale information. Using idealized synthetic data, we compare the constraining power of the full shape of the Lyα forest auto-correlation and its cross-correlation with quasars using the baseline continuum fitting analysis versus the true continuum. We find that knowledge of the true continuum enables a ∼ 10% reduction in uncertainties on the Alcock-Paczyński (AP) parameter and the matter density, Ωm.

Our analysis uses updated k-corrections and evolutionary corrections, including new polynomial kcorrection fits derived from BGS Year 1 data that supersede earlier GAMA-based prescriptions. Exploiting the statistical power of DESI, we measure LFs to very faint magnitudes, reaching $^{0.1}M_r-5\log h\sim -10$. Independent measurements from the North and South survey regions show excellent agreement around the LF knee, but the very small statistical uncertainties reveal that simple analytic forms fail to capture the full LF shape. The bright end departs from a pure exponential decline, while the faint end exhibits complex, non-powerlaw behaviour, including a pronounced upturn at $^{0.1}M_r-5\log h\gtrsim -15$, which is stronger for red galaxies than for blue.

An optical transient, AT2025ulz, was discovered within the localization region. AT2025ulz initially appeared to meet the expected behavior of kilonova emission, the telltale signature of a binary neutron star merger. The transient subsequently rebrightened after ∼5 days and was classified as a Type IIb supernova. In this work, we analyze the observations of its host galaxy obtained by the Dark Energy Spectroscopic Instrument (DESI). From the DESI spectrum, we obtain a secure redshift of z = 0.084840 ± 0.000006.

Using over 10,000 quasar pairs from the Dark Energy Spectroscopic Instrument (DESI) Year 1 data, with projected comoving separations r⊥ < 2h−1 Mpc, we investigate how the proximity zone of foreground quasars at z ∼ 2–3.5 affects Lyα absorption in their background quasars. The large DESI sample enables unprecedented precision in measuring this “transverse proximity” effect, allowing a detailed investigation of the signal’s dependence on the projected separation of quasar pairs and the luminosity of the foreground quasar.

These experiments are now so precise that they must account for the effects of the cavity containing the electron. Classical calculations of this “cavity shift” must subtract the electron’s divergent self-field, and thus require knowledge of the exact Green’s function for the cavity’s electromagnetic field. We perform the first fully quantum calculation of the cavity shift in a closed cavity, which instead involves subtracting linearly divergent cavity mode sums and integrals. Using contour integration methods, we find perfect agreement with existing classical results for both spherical and cylindrical cavities, justifying their current use.

The MC for the posterior will typically require evaluation of p(n) at arbitrary values of n, i.e., one needs to provide a density estimator over the full n space from the provided samples. But the high dimensionality of n hinders both the density estimation and the efficiency of the MC for the posterior. We describe a solution to this problem: a linear compression of the n space into a much lower-dimensional space u, which projects away directions in n space that cannot appreciably alter L. The algorithm for doing so is a slight modification to principal components analysis,... https://escholarship.org/uc/item/3015393q Tue, 4 Aug 2026 00:00:00 +0000 Bernstein, GM d’Assignies, W Troxel, MA Alarcon, A Amon, A Giannini, G Yin, B Aguena, M Allam, SS Andrade-Oliveira, F Brooks, D Rosell, A Carnero Carretero, J da Costa, LN Pereira, MES De Vicente, J Everett, S Frieman, J García-Bellido, J Gruen, D Hinton, SR Hollowood, DL Honscheid, K James, DJ Lee, S Marshall, JL Mena-Fernández, J Miquel, R Malagón, AA Plazas Sanchez, E Cid, D Sanchez Sevilla-Noarbe, I Shin, T Smith, M Suchyta, E Swanson, MEC Weaverdyck, N https://orcid.org/0000-0001-9382-5199 Weller, J Wiseman, P https://escholarship.org/uc/item/2x236352 The Lyman-α (Lyα) forest is a key tracer of large-scale structure at redshifts z > 2, traditionally studied using the spectra of luminous but relatively rare quasars. In this work, we explore the viability of using the fainter yet significantly more abundant Lyman Break Galaxies (LBGs) as alternative background sources for Lyα forest studies. We analyze 4,151 Lyα forest skewers extracted from LBG spectra obtained in the DESI pilot surveys conducted in the COSMOS and XMM-LSS fields. From this dataset, we present the first measurement of the Lyα forest auto-correlation function derived exclusively from LBG spectra, probing comoving separations up to 48 h -1 Mpc at an effective redshift of z eff = 2.70. The measured LBG Lyα forest auto-correlation is consistent with that derived from DESI DR2 quasar Lyα forest spectra at a comparable redshift, validating the use of LBGs as reliable background sources for Lyα forest analyses.

The Dark Energy Spectroscopic Instrument (DESI) BAO analysis for the first year (DR1) data uses the “standard” reconstruction framework, in which the displacement field is estimated from the observed density field by solving the linearized continuity equation in redshift space, and galaxy and random positions are shifted in order to partially remove non-linearities. There are several approaches to solving for the displacement field in real survey data, including the multigrid (MG), iterative Fast Fourier Transform (iFFT), and iterative Fast Fourier Transform particle (iFFTP) algorithms. In this work, we analyze these algorithms and compare them with various metrics including two-point statistics and the displacement itself using realistic DESI mocks.

A broad range of haloscope concepts has been developed, including resonant cavity haloscopes, lumped-element circuit detectors, and spin-based experiments, each sensitive to different axion couplings and mass ranges. Rather than attempting an exhaustive survey of all existing approaches, this comparative review provides a unified framework for the major haloscope classes, establishing a common language for the descriptions of signal generation, noise properties, analytical methodologies, and scanning strategies. Key properties of ultralight bosonic dark matter relevant for detection are summarized first, including coherence time, spectral linewidth, and stochasticity under the standard halo model.

For the gravitationally induced parity-even 4PCF, we detect a signal with a significance of using our fiducial setup. We assess the robustness of this detection through a series of validation tests, including auto and cross-correlation analyses, sky partitioning across multiple patch combinations, and variations in radial scale cuts. Due to the low completeness of the sample, we find that differences in fiber assignment implementation schemes can significantly impact estimation of the covariance and introduce biases in the data vector. After correcting for these effects, all tests yield consistent results. This is one of the first measurements of the connected 4PCF on the DESI LRG sample; the good agreement between the simulation and the data implies that the amplitude of the density fluctuation inferred from the connected 4PCF is consistent... https://escholarship.org/uc/item/1wg83331 Tue, 4 Aug 2026 00:00:00 +0000 Hou, J Cahn, RN Aguilar, J Ahlen, S Bianchi, D Brooks, D Claybaugh, T Doel, P Ferraro, S Forero-Romero, JE Gaztañaga, E Le Guillou, L Gutierrez, G Honscheid, K Huterer, D Ishak, M Joyce, R Juneau, S Kehoe, R Kirkby, D https://orcid.org/0000-0002-8828-5463 Kisner, T Kremin, A https://orcid.org/0000-0001-6356-7424 Lamman, C Landriau, M de la Macorra, A Manera, M de Mattia, A Miquel, R Mueller, E Nadathur, S Niz, G Percival, WJ Prada, F Pérez-Ràfols, I Ross, AJ Rossi, G Sanchez, E Schlegel, D Schubnell, M Seo, H Silber, J https://orcid.org/0000-0002-3461-0320 Slepian, Z Sprayberry, D Tarlé, G Weaver, BA Zou, H https://escholarship.org/uc/item/1k88d64c We derive constraints on the neutrino mass using a variety of recent cosmological datasets, including DESI BAO, the full-shape analysis of the DESI matter power spectrum and the one-dimensional power spectrum of the Lyman-α forest (P1D) from eBOSS quasars as well as the cosmic microwave background (CMB). The constraints are obtained in the frequentist formalism by constructing profile likelihoods and applying the Feldman-Cousins prescription to compute confidence intervals. This method avoids potential prior and volume effects that may arise in a comparable Bayesian analysis. Parabolic fits to the profiles allow one to distinguish changes in the upper limits from variations in the constraining power σ of the different data combinations. We find that all profiles in the ΛCDM model are cut off by the ∑mν ≥ 0 bound, meaning that the corresponding parabolas reach their minimum in the unphysical sector.

We focus on two well-known stellar overdensities in the anticenter: the Monoceros Ring (MRi) and Anticenter Stream (ACS). We find that the MRi overdensity has kinematic signatures consistent with a tidally induced spiral arm, a type of dynamic spiral arm created by an interaction with a satellite galaxy, most likely the Sagittarius dwarf spheroidal galaxy (Sgr). We use the kinematics of the MRi to calculate the two most recent passage times of Sgr, finding 0.25 ± 0.09 Gyr and 1.10 ± 0.23 Gyr from the present day. We validate that the ACS is kinematically decoupled from the MRi because they are moving in opposite radial and vertical directions.

A standard siren measurement with a nearby (luminosity distance ∼40 Mpc) event such as GW170817 is typically sensitive to the peculiar motion of the host galaxy owing to local dynamics. Previous measurements from this event have taken advantage of peculiar velocity measurements of nearby galaxies, including a handful of objects in the galaxy group that the host of the event, NGC 4993, has been associated with. Still, the group’s properties and NGC 4993’s membership were debated. We present DESI observations of thousands of galaxies in the vicinity of NGC 4993, resulting in 39 group galaxies and a fivefold increase in galaxies compared to previous observations, with many contributing to a peculiar velocity measurement.

To achieve a robust combination that accounts for the correlation between the two data releases, we employ the ShapeFit compression method and estimate the joint covariance using EZmocks. This compressed approach inherently mitigates the prior volume effects that have previously dominated Bayesian constraints from DESI data with minimal external priors. Consequently, we obtain — for the first time within a Bayesian framework — reliable DESI-only constraints on extensions to ΛCDM using only a Big Bang Nucleosynthesis prior on the baryon density and a wide prior on the spectral index.

Our axion-photon coupling incurs periodic corrections due to monopoles (equivalently UV instantons), which are large for light monopoles. Axion periodicity is manifestly duality invariant since the axion itself transforms under duality. Our model is the original Seiberg-Witten theory, which naturally hosts an -axion and light monopoles. We calculate the axion-photon amplitude in different duality frames and prove its duality invariance. https://escholarship.org/uc/item/3269p9m8 Tue, 28 Jul 2026 00:00:00 +0000 Csáki, Csaba Ovadia, Rotem Ruhdorfer, Maximilian Telem, Ofri Terning, John https://orcid.org/0000-0003-1367-0575 https://escholarship.org/uc/item/22f784cm A search is presented for emerging jets using 140fb-1$$140~\textrm{fb}^{-1}$$ of proton–proton collision data at s=13TeV$$\sqrt{s} = 13~\textrm{TeV}$$, collected by the ATLAS experiment between 2015 and 2018. The search looks for the existence of a dark sector with symmetries similar to those in quantum chromodynamics. This dark sector is populated with dark quarks, which undergo showering similar to quarks in the Standard Model, leading to a high multiplicity of long-lived dark hadrons within a dark jet. These dark hadrons subsequently decay to Standard Model particles via a new heavy scalar mediating particle ϕ$$\phi $$. This results in jets which contain multiple displaced vertices, known as emerging jets. This analysis targets four-jet topologies, with two emerging jets and two Standard Model jets, resulting from the decay of pair-produced scalar mediators.

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.

Leveraging the A BACUS S UMMIT simulation suite and the halo occupation distribution (HOD) formalism, we trained emulator models to describe the non-linear clustering of galaxies and velocities in redshift space. Our analysis demonstrates that combining galaxy and peculiar velocity clustering provides tighter constraints on both HOD and cosmological parameters, particularly on σ 8 and w 0 . We further applied our models to realistic mock catalogues, reproducing the expected density and peculiar velocity errors of type-Ia supernovae, Tully-Fisher and fundamental plane measurements for the combined ZTF and DESI measurements. While systematic biases arise in the HOD parameters, the cosmological constraints remain unbiased, yielding a 3.8% precision measurement on fσ 8 compared to 4.7% when using galaxy clustering alone.

Turning these simulations into stellar mock catalogues requires ‘upsampling’ the star particles into individual stars following the same phase-space density. In this paper, we introduce two new upsampling methods. First, we describe GalaxyFlow, a sophisticated upsampling method that utilizes normalizing flows to both estimate the stellar phase-space density and sample from it. Secondly, we improve on existing upsamplers based on adaptive kernel density estimation (KDE), using maximum likelihood estimation to fine-tune the bandwidth for such algorithms in a way that improves both the density estimation accuracy and upsampling results. We demonstrate our upsampling techniques on a neighbourhood of the Solar location in two simulated galaxies: Auriga 6 and h277.

The coefficients are measured as a function of transverse momentum ( ), collision centrality, and event multiplicity. They are extracted using two complementary methods: two-particle correlations with a template-fit subtraction of short-range nonflow contributions, and four-particle subevent cumulants, which intrinsically suppress nonflow effects and provide sensitivity to flow fluctuations. The results show a clear hierarchy and a nonmonotonic dependence on , reaching a maximum around , consistent with trends observed in heavy-ion collisions.

This polarization-shape alignment effect was previously observed in a small sample of local spirals. If this is prevalent for disk galaxies out to cosmological redshifts, novel measurements of cosmic birefringence and cosmic shear will be enabled by leveraging radio continuum surveys such as the Square Kilometre Array synergized with galaxy shape measurements. We calculate the polarization-shape misalignment angle for star-forming galaxies in the IllustrisTNG50 simulation at 0 < z < 2, assuming that additional polarized radio emission from an active galactic nucleus is negligible in at least a sizable fraction of the star-forming galaxies.

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).

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/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/7d78299d One of the forthcoming major challenges in particle physics is the experimental determination of the Higgs trilinear self-coupling. 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.

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).

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.

Using the anisotropic materials in the dataset, we further compute the level of daily modulation in interaction rates and the resulting directional sensitivities, highlighting materials with prospects to detect the dark matter wind. Our methods provide the basic tools for the data-driven design of dark matter detectors, and our findings lay the groundwork for the next generation of highly optimized direct searches for dark matter as light as the keV scale.

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/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. The results are obtained using the full Run II data sample collected with the Collider Detector at the Fermilab Tevatron, which corresponds to an integrated luminosity of 9.5 fb-1. The cross section is measured as a function of photon transverse energy, ETγ, in the range 30 https://escholarship.org/uc/item/4b81v8tf Wed, 3 Jun 2026 00:00:00 +0000 Aaltonen, T Albrow, MG Amerio, S Amidei, D Anastassov, A Annovi, A Antos, J Apollinari, G Appel, JA Arisawa, T Artikov, A Asaadi, J Ashmanskas, W Auerbach, B Aurisano, A Azfar, F Badgett, W Bae, T Barbaro-Galtieri, A Barnes, VE Barnett, BA Barria, P Bartos, P Bauce, M Bedeschi, F Behari, S Bellettini, G Bellinger, J Benjamin, D Beretvas, A Bhatti, A Bland, KR Blumenfeld, B Bocci, A Bodek, A Bortoletto, D Boudreau, J Boveia, A Brigliadori, L Bromberg, C Brucken, E Budagov, J Budd, HS Burkett, K Busetto, G Bussey, P Butti, P Buzatu, A Calamba, A Camarda, S Campanelli, M Canelli, F Carls, B Carlsmith, D Carosi, R Carrillo, S Casal, B Casarsa, M Castro, A Catastini, P Cauz, D Cavaliere, V Cerri, A Cerrito, L Chen, YC Chertok, M https://orcid.org/0000-0002-2729-6273 Chiarelli, G Chlachidze, G Cho, K Chokheli, D Clark, A Clarke, C Convery, ME Conway, J Corbo, M Cordelli, M Cox, CA Cox, DJ Cremonesi, M Cruz, D Cuevas, J Culbertson, R d’Ascenzo, N Datta, M de Barbaro, P Demortier, L Deninno, M D’Errico, M Devoto, F Di Canto, A Di Ruzza, B Dittmann, JR Donati, S D’Onofrio, M Dorigo, M Driutti, A Ebina, K Edgar, R Erbacher, R Errede, S 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/2km9t4wr We present two approaches for “painting” baryonic properties relevant to the Sunyaev-Zel’dovich (SZ) effect—optical depth and Compton-y—onto three-dimensional N-body simulations, using the MillenniumTNG suite as a benchmark. 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. Additionally, we assess how well the reconstructed fields correlate with dark matter haloes across various mass thresholds. The results indicate that the transfer function method yields... https://escholarship.org/uc/item/2km9t4wr Wed, 27 May 2026 00:00:00 +0000 Liu, R Henry Hadzhiyska, Boryana Ferraro, Simone https://orcid.org/0000-0003-4992-7854 Bose, Sownak Hernández-Aguayo, César
