However, evidence from the learning sciences and beyond has shown that focusing only on the extent to which datasets reflect students’ lived experiences does not fully explain whether or how students build relationships with data. In this study, we present syncretic data storytelling as a pedagogical approach that brings together different types of knowledge—personal experience, patterns from quantitative datasets, and analysis of the social, political, and historical context—to provide multiple pathways for students to build relationships with data. We illustrate this approach by exploring three student cases from a data storytelling workshop on the topic of environmental racism. In each case, the focal student initially did not connect with the provided geospatial dataset, but later used quantitative... https://escholarship.org/uc/item/67b452fx Sat, 31 Oct 2026 00:00:00 +0000 Reigh, Emily V McBride, Cherise Escudé, Meg Roberto, Collette Gutiérrez, Kris Wilkerson, Michelle Hoda https://escholarship.org/uc/item/4jn5851b ABSTRACT This paper examines a professional learning (PL) program for upper elementary teachers focused on developing instructional practices to support multilingual learners (MLLs) in science. The PL sought to support teachers' praxis, which we describe as their sense of agency to critically analyze and take action against barriers to MLLs’ opportunities to learn. We analyzed pre‐PL interviews with teachers to identify the ways that they framed MLLs from asset‐ and deficit‐based perspectives and the barriers that they identified that undermine MLLs' science learning. Then, we analyzed the extent to which the teachers' participation in the PL shifted their framing of MLLs and fostered their sense of agency to challenge the barriers faced by MLLs. We found that teachers shifted toward more asset‐based views of students' existing language resources and deepened their sense of agency to employ scaffolds that engage these resources in their own instructional practice. However, teachers... https://escholarship.org/uc/item/4jn5851b Sat, 31 Oct 2026 00:00:00 +0000 Reigh, Emily V Miller, Emily Adah Fackler, Ayça K Simani, Maria Chiara https://escholarship.org/uc/item/1f34s38v ABSTRACT Culturally relevant pedagogy (CRP) is an approach to teaching that challenges the inequitable structures that create an education debt for minoritized students. Many studies of CRP in science education focus on teachers' philosophies and dispositions; fewer studies have focused on enacted teaching practice, such as the use of curricular resources. CRP requires that teachers take an oppositional stance toward curricula and actively reconstruct them to center the cultures of their students. In this study, we use ethnographic methods informed by Ladson‐Billings' original work to investigate one teacher's implementation of a large‐scale science curriculum in a Spanish‐English dual‐language immersion class that serves Latine students. We illustrate the teacher's enactment of the conceptions of CRP, showing how she drew from the curricular resources and also diverged from them at different grain sizes, including (a) in‐the‐moment divergence from prescribed teacher moves, (b)... https://escholarship.org/uc/item/1f34s38v Sat, 31 Oct 2026 00:00:00 +0000 Miller, Emily Adah Reigh, Emily V Mathis, Clausell https://escholarship.org/uc/item/19v2x6xv Teaching about climate change and its impacts, like precipitation extremes, requires linking complex science concepts with consequential issues of justice for both human communities and natural ecosystems. However, teachers have few professional learning opportunities or curricular resources that address the intersection of science and sociopolitical systems content with a justice lens. In this article, we describe the design of a five-day summer institute for PK-12 teachers in the San Francisco Bay Area that was developed by a large team of teachers, informal educators, environmental justice activists, scientists, and education researchers. We present the conceptual framework for our design, a set of environmental justice lenses, and highlight three activities from the institute that focus on local impacts of precipitation extremes in urban environments, all of which can be adapted to different grade levels and teaching contexts. We also describe our iterative design process... https://escholarship.org/uc/item/19v2x6xv Sat, 31 Oct 2026 00:00:00 +0000 Reigh, Emily V Barton, Jacob C Dunhill, Gita Gallagher, Kate Loebl, Stuart Fitzmaurice, Helen L https://escholarship.org/uc/item/8g58h588 Global observations of ocean color from space provide a unique capability to conduct multi-decadal studies of biogeochemical constituents and processes in the upper ocean layers at the regional, basin, and global scales. The concentration of particulate organic carbon (POC) in the surface ocean waters is one of the biogeochemically important data products derivable from satellite ocean color observations. The data record of standard global POC product is available from NASA and has been obtained from the empirical power-function relationship between POC and a single blue-to-green band ratio of ocean remote-sensing reflectance, R rs(λ), which is here referred to as the BR-PF algorithm. Recently, we formulated a new suite of satellite ocean-color sensor-specific global POC algorithms that are referred to as hybrid algorithms because they contain two components, one based on the maximum band-ratio (MBR) and the other on the band ratio difference index (BRDI) of reflectance (Stramski... https://escholarship.org/uc/item/8g58h588 Fri, 30 Oct 2026 00:00:00 +0000 Joshi, Ishan D Stramski, Dariusz Reynolds, Rick A https://orcid.org/0000-0002-1579-3600 Robinson, Dale H https://escholarship.org/uc/item/6pm527mh Loop-Free Routing in Computer Networks and the Internet&nbsp; https://escholarship.org/uc/item/6pm527mh Fri, 30 Oct 2026 00:00:00 +0000 Garcia-Luna-Aceves, J.J.

These climate-carbon cycle feedbacks determine the long-term Earth System response to biological evolution, geologic drivers, and events such as anthropogenic fossil fuel use. In Section “Earth's carbon cycle” of this chapter we outline the reservoirs and chemistry of carbon in Earth's surface environment; in Section “Carbon fluxes and dynamic balances” we describe the dynamics underpinning carbon cycle feedbacks, including a discussion of carbon cycle models, and in Section “Climate and the carbon cycle” we survey the observational evidence base for our current understanding of long-term Earth System change by focusing on available proxy records and reconstructions of the climate and carbon cycle across the Cenozoic Era.

Current research seeks to understand the relationship of the ocean's biological pump to the Earth's environmental, chemical, and climatic history. Changes in the efficiency of the biological pump are central to most current hypotheses for the cause of the coherent variations of atmospheric CO2 over the ice age climate cycles (i.e., glacial vs. interglacial stages). Here, we review the concepts, tools, and observations relating to this topic. While the biological pump is driven by biological activity in the sunlit surface ocean, its global efficiency is shown to be affected by the ocean's physical circulation, and its net effect on atmospheric CO2 is shown to work through the ocean's acid–base chemistry. We integrate these... https://escholarship.org/uc/item/4545w31k Thu, 29 Oct 2026 00:00:00 +0000 Hain, MP https://orcid.org/0000-0002-8478-1857 Sigman, DM Haug, GH https://escholarship.org/uc/item/328287pg The concentrations of the major cations (esp., Ca 2+ , Mg 2+ ) in Earth's oceans have undergone large-scale fluctuations in the geological past. This is important because the key geochemical properties of the marine environment that underpin the global carbon cycle – the aqueous carbonate system equilibria and solubility of solid calcium carbonate (CaCO 3 ) – are heavily influenced by ion-pairing, which in turn depends on the activity of the major cations and anions. An appropriate interpretation of marine proxies as well as the reconstruction of past states of ocean geochemistry and carbon cycle across geologic events requires that these effects are considered. However, most current global carbon cycle models use empirical carbonate system dissociation constants fitted to laboratory experiments with present-day seawater major cation and anion concentrations and in the few simulations of global carbon cycling that have accounted for paleo-seawater composition, only relatively... https://escholarship.org/uc/item/328287pg Thu, 29 Oct 2026 00:00:00 +0000 Adloff, Markus Ganey, Terra M Hain, Mathis P https://orcid.org/0000-0002-8478-1857 Henehan, Michael J Greene, Sarah E Ridgwell, Andy https://escholarship.org/uc/item/1vf3s6xk Abstract There is currently no explanation or carbon cycle model scenario for severe radiocarbon ( 14 C) depletion reconstructed in the intermediate depth eastern tropical North Pacific Ocean (ETNP) at the end of the last ice age. Here, we develop new constraints on hypothesized geologic carbon release based on the boron isotope pH proxy and regional refinement of a global carbon cycle model. We find that pH‐neutral release of ∼800 Pg C over 5,000&nbsp;years can produce the radiocarbon anomalies in the ETNP while inducing neither a large pH anomaly nor CaCO 3 dissolution (as observed) and causing minimal atmospheric CO 2 rise. Mass‐balance considerations dictate that the anomalous carbon was concentrated near the geologic source in the ETNP without significantly affecting radiocarbon‐based reconstructions of global ocean circulation change. Plain Language Summary At the end of the last ice age, unusually low levels of radiocarbon were found in ocean waters off the west coast... https://escholarship.org/uc/item/1vf3s6xk Thu, 29 Oct 2026 00:00:00 +0000 Green, RA Rafter, PA Sun, C Gray, WR Rae, JWB Pelly, M Xu, C Thirumalai, K Southon, JR Pavia, F Hain, MP https://orcid.org/0000-0002-8478-1857 https://escholarship.org/uc/item/0rt8r861 Abstract Proxy records of seawater radiocarbon ( 14 C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO 2 during the termination of the last ice age (≈18,000‐to‐12,000&nbsp;years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14 C/C in the intermediate‐depth Eastern Tropical North Pacific (ETNP) near the Gulf of California (GoC). This deglacial ETNP 14 C/C anomaly is hypothesized to reflect either (a) an artifact of the proxy record, (b) the advection of low 14 C/C seawater, or (c) the input of 14 C/C‐depleted geologic carbon related to local seafloor volcanism. To test these hypotheses, we first use new sediment‐trap and seaweed 14 C/C to establish a new baseline understanding of ETNP seawater 14 C/C, which suggest that anomalously low 14 C/C is upwelled in the modern GoC. We then apply new geochemical experiments to test and ultimately validate the utility... https://escholarship.org/uc/item/0rt8r861 Thu, 29 Oct 2026 00:00:00 +0000 Rafter, Patrick A Hain, Mathis P https://orcid.org/0000-0002-8478-1857 Arellano‐Torres, Elsa Thirumalai, Kaustubh Tappa, Eric J Machain‐Castillo, Maria L Soto‐Jimenez, Martin DeVries, Tim Hendy, Ingrid L Herguera, Juan C Gray, William R Green, Ryan A Pavia, Frank Rae, James WB Southon, John R https://escholarship.org/uc/item/19w1j0s1 Barrier epithelia are shielded from the external environment by their apical extracellular matrices (aECMs). The molecular complexity of aECMs has challenged understanding of their organization in vivo. To define the molecular architecture of a model aECM we generated a toolkit of 105 fluorescently tagged aECM components using gene editing in C. elegans, focusing on proteins secreted by the epidermis to form the collagen-rich cuticle. We developed efficient pipelines for modular protein tagging and rapid fluorophore swapping. Most tagged collagens were functional and exhibited exquisitely specific patterning across stages, cell types, and matrix substructures. We define multiple reference markers for key substructures including the little-understood cortical layer, as well as the helical crossed fiber arrays that function as a hydrostatic skeleton to maintain organismal shape. We further tagged 30 members of key aECM protein classes including proteases, protease inhibitors, and... https://escholarship.org/uc/item/19w1j0s1 Wed, 28 Oct 2026 00:00:00 +0000 Ragle, James Matthew Pooranachithra, Murugesan Ashley, Guinevere E Cadena, Emma Blank, Batia Kang, Katelyn Chen, Cincy Bhowmick, Aditree R Mercado, Soraya H Wells, Tabatha E Clancy, John C Chisholm, Andrew D Ward, Jordan D https://orcid.org/0000-0001-9870-8936 https://escholarship.org/uc/item/6q5331pb A search for leptoquark signals is performed in final states with a hadronically decaying τ-lepton and missing transverse momentum, using data from proton–proton collisions at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider during Run 2 (2015–18), corresponding to an integrated luminosity of 140 fb − 1 . The analysis is designed to probe both resonant production and non-resonant t-channel exchange of the leptoquark, covering a wide range of coupling scenarios. No excess above the Standard Model background prediction is observed.

The data are collected with the ATLAS detector at the LHC in proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV, corresponding to an integrated luminosity of 140 fb-1. Differential cross-sections are presented as a function of the transverse momentum of the b-jet for both the electron and muon decay modes of the W boson. The results corrected for all detector effects are presented in a fiducial region defined with basic lepton and jet kinematics, and compared with theoretical predictions. The combined fiducial cross-section of W + b-jets for the electron and muon channels is measured to be 16.6 ± 1.9 pb, which is consistent with the next-to-leading-order QCD prediction of 16.8 ± 2.3 pb.

Events in which one of the τ -leptons decays into a muon and two neutrinos τ→ντν¯μμ$$ \tau \to { u}_{\tau }{\overline{ u}}_{\mu}\mu $$ are selected and are categorized into three regions by the presence of an electron or either one or three charged-particle track(s) from the second τ-lepton decay. The measurement is performed in events where both Pb ions remain intact and no neutrons are emitted. Differential cross-sections are measured for seven variables in three fiducial regions at particle level.

Contributing analyses include measurements of vector-boson scattering in numerous final states as well as a tri-boson measurement. The combined measurement is used to constrain anomalous electroweak boson quartic self-couplings that result from dimension-8 operators in the Éboli model using an effective field theory. Results are presented as 68% and 95% confidence level intervals parameterised by one or two Wilson coefficients, both with and without unitarity constraints applied. Theoretical bounds from unitarity and positivity are overlaid where relevant.

Cell type-specific manipulation further demonstrated that 5-HT2AR signaling in cortical layer 5 pyramidal neurons is necessary and sufficient for psilocybin-induced synaptic remodeling but dispensable for the head-twitch response, a rodent proxy of hallucination. https://escholarship.org/uc/item/8vj269hr Thu, 22 Oct 2026 00:00:00 +0000 Baker, Jacob J Kogan, Emily Ma, Shaorong Lu, Ju Zuo, Yi https://orcid.org/0000-0001-9020-0003 https://escholarship.org/uc/item/5jb903xf Season 1, Week 3 -&nbsp;What are the decision points during the publishing process? https://escholarship.org/uc/item/5jb903xf Thu, 22 Oct 2026 00:00:00 +0000 Stuit, Martha https://escholarship.org/uc/item/5cj055xb Season 2, Week 2 -&nbsp;Journal vs. Publisher https://escholarship.org/uc/item/5cj055xb Thu, 22 Oct 2026 00:00:00 +0000 Stuit, Martha https://escholarship.org/uc/item/4r0316tw Season 2, Week 1 -&nbsp;Where do I even start with publishing an article? https://escholarship.org/uc/item/4r0316tw Thu, 22 Oct 2026 00:00:00 +0000 Stuit, Martha https://escholarship.org/uc/item/49q2b8wr Season 1, Week 5 -&nbsp;How do I get support for the cost of open access publishing? https://escholarship.org/uc/item/49q2b8wr Thu, 22 Oct 2026 00:00:00 +0000 Stuit, Martha https://escholarship.org/uc/item/44k817qd Season 1, Week 6 -&nbsp;Can I use this thing in my article without violating copyright?

Commonly, species' range shifts are observed by analyzing changes in occurrence or abundance data through time, or predicted across different climate change scenarios by modeling species' climatic niches. However, it remains unclear how well these climate-based forecasts align with empirically documented range shifts from monitoring efforts. Here, we tested the congruence between modeled range shifts, predicted using climatic niche models, and documented range shifts, derived from empirical observations collected over recent decades, for more than 9,500 range shifts across over 3,500 marine and terrestrial species. We found that documented and modeled range shifts tend to align in latitudinal direction, with greater alignment for marine (76%) than terrestrial (56%) cases. However, even when the directions aligned, documented shifts exceeded modeled shifts... https://escholarship.org/uc/item/9s90549w Wed, 14 Oct 2026 00:00:00 +0000 Oliveira, Brunno F Bertrand, Romain Pinsky, Malin L https://orcid.org/0000-0002-8523-8952 Casajus, Nicolas Wolfe, Barrett W Scheffers, Brett R Villalobos, Fabricio Grenouillet, Gaël Pecl, Gretta T Chen, I-Ching Baecher, J Alex Lawlor, Jake A Sunday, Jennifer Murienne, Jérôme Rolland, Jonathan Thompson, Laura M Lancaster, Lesley T Rubenstein, Madeleine A Moore, Nikki A Bandara, RMWJ Diamond, Sarah E Weiskopf, Sarah R Lenoir, Jonathan Comte, Lise https://escholarship.org/uc/item/1753z82j Marine ecosystems in peril: Time to prepare for super El Niño https://escholarship.org/uc/item/1753z82j Wed, 14 Oct 2026 00:00:00 +0000 Bruno, John F Burrows, Michael T Doney, Scott C Frölicher, Thomas L Kubiszewski, Ida Gibert, Jean P Lenton, Timothy M Meredith, Michael Pinsky, Malin L https://orcid.org/0000-0002-8523-8952 Rae, James WB Romanou, Anastasia Smale, Dan A Zeff, Maya https://escholarship.org/uc/item/9dq620rc The first observation of a new meson state decaying into and a photon is presented using a dataset of collisions at a center-of-mass energy collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of . The mesons are reconstructed from a three-muon final state from decays, along with photons reconstructed via conversions to electron-positron pairs in the detector material. The new state is observed with a significance that exceeds 8 standard deviations. The mass difference between the new meson state and the ground-state meson is measured to be . This corresponds to a mass for the observed state of , where the last uncertainty is due to the precision of the best knowledge of the meson mass.

Both efforts are based on a data sample corresponding to 164 fb−1 of s=13.6$$ \sqrt{s}=13.6 $$ TeV proton-proton collisions recorded by the ATLAS experiment at the Large Hadron Collider. The first study employs matrix-element-based optimal observables to constrain CP-odd couplings beyond the Standard Model within the Standard Model Effective Field Theory framework, expressed in the Warsaw basis. The second study exploits angular distributions to probe the Higgs boson’s couplings to longitudinally and transversely polarised W and Z bosons in the production of the Higgs boson. To maximise the sensitivity, the constraints of the CP-odd couplings are combined with those from a previous analysis performed in γγjj events in a data sample of proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV, corresponding to an integrated luminosity of 140 fb−1.

These lead to photon-induced interactions that are observed in ultra-peripheral collisions (UPCs), such as vector meson and lepton-pair production. The high photon flux also enables the occurrence of multiple photon-induced processes in a single collision. Presented is the first measurement of the coincident production of γ γ → μ + μ − and γ + A → ρ 0 + A in UPC Pb+Pb collisions at centre-of-mass energies of 5.02 TeV and 5.36 TeV with the ATLAS detector at the Large Hadron Collider. The coincident ρ 0 is identified via its decay into a π + π − pair, with the selected π + π − sample also containing the non-resonant continuum contribution.

Caenorhabditis elegans is an excellent model for studying sperm motility, due to the worm's transparency and high sperm production. C. elegans amoeboid sperm move by extending and retracting pseudopods, which are powered internally by the dynamic polymerization and depolymerization of the nematode Major Sperm Protein (MSP). Previous biochemical studies in the parasitic nematode Ascaris suum identified MSP polymerization-activating kinase (MPAK) as a key regulator of MSP assembly within the pseudopod. Here we investigate two C. elegans homologs, Tau Tubulin Kinase 8.1 (ttbk-8.1) and Tau Tubulin Kinase 8.2 (ttbk-8.2), that arose from a C. elegans-specific gene duplication.

This paper studies micro-irrigation systems (MIS), a technology thought to reduce the energy required for irrigation by as much as 70 percent. We installed individual meters to directly measure the energy consumption of several hundred farmers in Gujarat, India, and linked the meter data with survey data to yield a uniquely comprehensive view into energy use patterns in smallholder agriculture. We document two facts. One, energy use varies widely across farmers, and this variation is unexplained by factors such as farm area or village geography. Two, MIS users in our sample consume 30 to 40 percent more energy than non-users of MIS. This difference does not appear to be fully explained by observable differences across farmers nor by rebound effects, suggesting that the energy efficiency gains of MIS under real-world conditions may be disappointing.

Higher-valent oxyacids of heavier main-group elements readily polymerize because of their ability to expand their coordination spheres and the polarity of their terminal E–O (E = P, As, Sb, Bi) bonds. As a result, no free R2SbO2H stibinic acids have yet been prepared. Lower-valent R2SbOH stibinous acids should be less susceptible to such polymerization, but there are no reported rational syntheses of molecules belonging to this class. We report here the first controlled synthesis and isolation of a molecular stibinous acid, Dipp2SbOH, where Dipp = 2,6-diisopropylphenyl. We also report an initial exploration of the chemistry of this class of compounds, including their Brønsted acidity and Lewis basicity. The hydroxyl group of Dipp2SbOH is weakly acidic as probed via reaction with the very strong base DBU.

The potentialities of early Sikhism became manifest through new usages in the Guru Granth of longstanding terms within Indian traditions. Steeped in pluralism, dialogism, musicality, and secularity, the orientations toward newness were undermined by the intervention of Ernst Trumpp’s colonially commissioned philology and the ramifications of his mistranslation of Sikh scripture, triggering diverse predicaments premised on the politics of recognition in late colonial India. https://escholarship.org/uc/item/7dg4p3kw Thu, 8 Oct 2026 00:00:00 +0000 Sahota, GS https://escholarship.org/uc/item/7334g58p Apical extracellular matrices (aECMs) are associated with many epithelia and often form a protective layer against biotic and abiotic threats in the environment. Despite their importance, we lack a deep understanding of their structure and dynamics in development and disease. Caenorhabditis elegans molting offers a powerful entry point to understanding developmentally programmed aECM remodeling. Here, we show that the poorly characterized putative protease inhibitor gene mlt-11 is directly regulated by the NHR-23 transcription factor. We identify key cis-regulatory elements required for robust mlt-11 expression. An internal MLT-11::mNeonGreen translational fusion transiently localized to the aECM in the cuticle and embryo. MLT-11::mNeonGreen also lined openings to the exterior (vulva, rectum, and mouth). mlt-11 is necessary to pattern all layers of the adult cuticle, and reduction of MLT-11 levels disrupted the barrier function of the cuticle.

Molecular surveillance of coastal phytoplankton and bivalve biotoxins could be used to link chl-a with HAB risk, but requires an understanding of whether the HAB risks increase uniformly as chl-a rises, or whether some taxa are disproportionately favored, and if these relationships vary by season. In this study, we present a novel use of molecular abundance data to investigate the scientific bases for estuarine chl-a thresholds protective against HABs. In San Francisco Bay (SFB), California, the relationship between molecular relative abundance (as measured by 18S metabarcoding) of nine different HAB taxa, absolute quantitative polymerase chain reaction (qPCR) abundance, and mussel toxin concentrations of a subset of the taxa were investigated for thresholds as a function of increasing... https://escholarship.org/uc/item/4bf642xq Thu, 8 Oct 2026 00:00:00 +0000 Killam, Daniel Bouma-Gregson, Keith Sutula, Martha Kudela, Raphe https://orcid.org/0000-0002-8640-1205 Hagy, James Anderson, Stephanie Senn, David https://escholarship.org/uc/item/0g07h182 The mammalian protein PERIOD (PER) and its C. elegans orthologue LIN-42 have been proposed to constitute an evolutionary link between two distinct, circadian and developmental, timing systems. While the function of PER in animal circadian rhythms is well understood molecularly and mechanistically, this is not true for LIN-42’s function in timing rhythmic development, reflected in C. elegans molting cycles. We observed arrhythmic molts upon combined deletion of a region comprising two distinct sequence elements previously termed SYQ and LT. This region functions as a casein kinase I (CK1)-binding domain (CK1BD) mediating stable binding to KIN-20, the C. elegans CK1δ/ε orthologue. CK1 phosphorylates LIN-42, and the CK1BD sub-domains SYQ/CKBD-A and LT/CKBD-B play distinct roles in controlling CK1-binding and kinase activity in vitro.

Drawing on the expertise of many scholars who were formerly tasked with producing the Sixth NCA and authors of other national or sub‐national climate... https://escholarship.org/uc/item/3tz7t05d Wed, 7 Oct 2026 00:00:00 +0000 Kenney, Melissa A Kopp, Robert E Samaras, Constantine Alberti, Marina Angell, Sonia Y Burney, Jennifer Cunliff, Colin Duffy‐Anderson, JT Fischer, Laura West Frey, Serita D Hicke, Jeffrey A Howard, Peter H Jerolleman, Alessandra Kirchhoff, Christine J Koebele, Elizabeth A Mahowald, Natalie M Misarti, Nicole Pearson, Dharshani L Phillips, Alexandra A Siders, AR Singh, Prabhjot K Smith, Nicholas G Teneva, Lida T Ulrich‐Schad, Jessica D Volenec, Jeffrey J Akamani, Kofi Alexander, Alisa J Anderson, Claire E Arbuckle, JG Auffhammer, Maximilian Avery, Christopher W Baker, Shalanda H Balk, Deborah Barbato, Michele https://orcid.org/0000-0003-0484-8191 Barnard, Patrick L https://orcid.org/0000-0003-1414-6476 Basaraba, Alexander B Bednar, Dominic J Bell, Jesse E Gayle, D Bennett Daniels, Laprisha Berry Bertrand, Darrian Bistline, John ET Brelsfoard, Corey L Briceno, Tania Burkett, Maxine Burnham, Michael Callahan, John A Cannon, Clare EB https://orcid.org/0000-0002-5507-5312 Carothers, Courtney Carter, Rebecca H Cawley, Max Mijin, J Chang, Howard H Chang, Michael H Chegwidden, Oriana S Chen, Kai Cheng, Brian S Chi, Guangqing Chu, Eric K Cleetus, Rachel Connor, Anna Cook, Amelia A Council, Dontá Cromar, Kevin R Curtis, Katherine J Daigle, John J Roney, Christopher DeLyser Domingue, Simone J Drake, John E Ebi, Kristie L Elias, Emile H Fann, Neal L Fleishman, Erica Gall, Elliott T Ghitis, Eliza Gilmore, Elisabeth A Gopalakrishnan, Sathya Grafton, Daniel Gray, SA Griffis, Roger B Grimm, Nancy B Hadjimichael, Antonia Han, Xueying Haverkamp, Jamie A Hess, Jeremy J Hessburg, Paul F Hinton, Kristen Averyt Hondula, David M Hubbell, Bryan Hultman, Nathan Jean, Cassandra Jinnah, Sikina https://orcid.org/0000-0003-4528-3000 Johnson, Jeremiah X Johnson, Steven Mana'oakamai Johnson, Victoria A Jones, Kristal Kaplan, P Ozge Kay, Samuel Keenan, Jesse M Keith, Ladd https://escholarship.org/uc/item/9fc3d2xd The Gaussian process is a common model in a wide variety of applications, such as environmental modeling, computer experiments, and geology. Two major challenges often arise: First, assuming that the process of interest is stationary over the entire domain often proves to be untenable. Second, the traditional Gaussian process model formulation is computationally inefficient for large datasets. In this paper, we propose a new Gaussian process model to tackle these problems based on the convolution of a smoothing kernel with a partitioned latent process. Nonstationarity can be modeled by allowing a separate latent process for each partition, which approximates a regional clustering structure. Partitioning follows a binary tree generating process similar to that of Classification and Regression Trees. A Bayesian approach is used to estimate the partitioning structure and model parameters simultaneously. Our motivating dataset consists of 11918 precipitation anomalies.

As predicted in the literature, our campus found that changing questions to focus more on student direct observation and metacognitive reflection, as well changing to a frequency scale, was correlated with an increase in favorable ratings for instructors who are women or from under-represented populations. We compare data from a full year of an older question set to a full year of a revised question set. Our campus focuses on the percent of responses in the top two (of five) categories as a summary of student feedback. A logistic regression analysis shows that the gaps between populations of instructors change significantly over the time of the change in questions. https://escholarship.org/uc/item/7kw8r33q Mon, 5 Oct 2026 00:00:00 +0000 Li, Yunzhe Lee, Herbert KH https://orcid.org/0000-0003-1087-4150 https://escholarship.org/uc/item/8jf60329 The protocols currently in place for routing within autonomous systems (ASes) of the Internet (e.g., OSPFv2, IS-IS, EIGRP and RIPv2) lack confidentiality and are &nbsp;vulnerable to many cyber attacks.

The events are selected with one charged lepton (electron or muon) and at least four jets. The differential cross-sections are presented at particle level as functions of several jet observables, including angular correlations, jet transverse momenta and invariant masses of the jets in the final state, which characterise the kinematics and dynamics of the top-antitop system and the hard QCD radiation in the system with associated jets. The typical precision is 5%–15% for the absolute differential cross-sections and 2%–4% for the normalised differential cross-sections. Next-to-leading-order and next-to-next-to-leading-order QCD predictions are found to provide an adequate description of the rate and shape of the jet-angular observables.... https://escholarship.org/uc/item/9mf0630m Wed, 30 Sep 2026 00:00:00 +0000 Aad, G Abbott, B Abeling, K Abicht, NJ Abidi, SH Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS 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 Agarwala, J Aggarwal, A Agheorghiesei, C Ahmad, A Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Aitbenchikh, B Aizenberg, I Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J 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, JF Allendes Flores, CA Allport, PP Aloisio, A Alonso, F Alpigiani, C Alvarez Estevez, M Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amor Dos Santos, SP Amos, KR Ananiev, V Anastopoulos, C Andeen, T Anders, JK Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Anthony, MT Antipov, E Antonelli, M Anulli, F Aoki, M Aoki, T Aparisi Pozo, JA Aparo, MA https://escholarship.org/uc/item/99v5x374 The ATLAS detector at the LHC recorded 0.49 nb−1 of Pb+Pb collisions and 25 pb−1 of pp collisions, both at the center-of-mass energy 5.02 TeV per nucleon pair. Recently, ATLAS also recorded 3μb−1 of Xe+Xe collisions at the center-of-mass energy 5.44 TeV, which provides a new opportunity to study the system-size dependence of the charged-hadron production in heavy-ion collisions. The large acceptance of the ATLAS detector allows to measure the spectra of charged hadrons in a wide range of pseudorapidity and transverse momentum. The nuclear modification factors R AA are constructed as a ratio of the spectra measured in Pb+Pb or Xe+Xe collisions to that measured in pp collisions. The R AA obtained in the two systems are presented for different centrality intervals and the results are discussed. https://escholarship.org/uc/item/99v5x374 Wed, 30 Sep 2026 00:00:00 +0000 Balek, Petr Collaboration, ATLAS https://escholarship.org/uc/item/92b9d1kq In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. This report describes the FCC integrated programme, which consists of two stages: an electron-positron collider (FCC-ee) in the first phase, serving as a high-luminosity Higgs, top, and electroweak factory; followed by a proton-proton collider (FCC-hh) at the energy frontier in the second phase. The FCC-ee is designed to operate at four key centre-of-mass energies: the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold—each delivering the highest possible luminosities to four experiments. Over 15 years of operation, FCC-ee will produce more than 6 trillion Z bosons, 200 million WW pairs, nearly 3 million Higgs bosons, and 2 million top anti-top pairs. Precise energy calibration at the Z pole and WW threshold will be achieved through... https://escholarship.org/uc/item/92b9d1kq Wed, 30 Sep 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, A Janot, P Lourenço, C Mangano, M Otto, T Poole, J Rajagopalan, S Raubenheimer, T Todesco, E Ulrici, L Watson, T Wilkinson, G 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 Alcaraz Maestre, J 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 Arias Alonso, B Arnaez, O Arnaldi, R Arneodo, F Arnold, H Arrutia Sota, P Ascioti, ME Assamagan, KA Aumiller, S Aydın, G Azizi, K Azzi, P Bacchetta, N Bacci, A Bai, B Bai, Y Balconi, L Baldinelli, G Balhan, B Ball, AH Ballarino, A https://escholarship.org/uc/item/8zz686g8 The Image Sources and Credits information section was missing from this article and should have read ‘The FCC Project formally acknowledges and credits all organisations and contributors whose data and imagery form part of the basemaps used in this work.

This analysis is based on proton-proton collision data recorded at s$$ \sqrt{s} $$ = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb−1. After selecting events containing large-radius jets with high track multiplicity, the invariant mass distribution of the two highest-transverse-momentum jets is scanned to look for an excess above a data-driven estimate of the Standard Model multijet background. No significant excess of events is observed and the results are thus used to set 95% confidence-level upper limits on the production cross-section times branching ratio of the Z′ to dark quarks as a function of the Z′ mass for various dark-quark scenarios. https://escholarship.org/uc/item/8br8s2cx Wed, 30 Sep 2026 00:00:00 +0000 Aad, G Abbott, B Abeling, K Abicht, NJ Abidi, SH Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS 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 Agarwala, J Aggarwal, A Agheorghiesei, C Ahmad, A Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Aitbenchikh, B Aizenberg, I Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J 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, JF Allendes Flores, CA Allport, PP Aloisio, A Alonso, F Alpigiani, C Alvarez Estevez, M Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amor Dos Santos, SP Amos, KR Ananiev, V Anastopoulos, C Andeen, T Anders, JK Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Anthony, MT Antipov, E Antonelli, M Anulli, F Aoki, M Aoki, T Aparisi Pozo, JA Aparo, MA https://escholarship.org/uc/item/890370h9 This paper presents differential cross-section measurements of events containing a charged lepton, missing transverse momentum, two b-jets, and two light jets, consistent with the W+W−bb¯$$ {W}^{+}{W}^{-}b\overline{b} $$ final state.

Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables.

The measurement is performed using the full Run-2 dataset, recorded from 2015 to 2018, of proton-proton collisions at a center-of-mass energy of 13&nbsp;TeV, corresponding to an integrated luminosity of 140  fb^{-1}. The fully leptonic final state with four leptons and one photon is analyzed, pp→ZZγ→ℓ^{+}ℓ^{-}ℓ^{'+}ℓ^{'-}γ with ℓ,ℓ^{'}=e or μ. This final state is measured in a fiducial region where photon final-state radiation is minimized, and the photon has a transverse momentum of p_{T}^{γ}&gt;20  GeV. Eight events are selected, with a background estimate of 0.92±0.15. This results in an observed (expected) significance of the ZZγ final state of 4.4σ (4.0σ).

The analysis is based on the definition of 101 distinct signal regions using machine-learning techniques.

Cross-sections for gluon-gluon fusion, vector-boson fusion, associated production with a W or Z boson, and top associated production processes are reported. An upper limit of 10 times the Standard Model prediction is set for the associated production process of a Higgs boson with a single top quark, which has a unique sensitivity to the sign of the top quark Yukawa coupling.

Because photons do not carry color charge, they are unaffected by the medium, and thus provide information about the momentum, direction, and flavor (quark or gluon) of the asso- ciated hard-scattered parton before it begins to shower and become quenched. In particular, the presence of a high-p T photon can be used to select pp and Pb+Pb events with the same configuration before quenching, limiting the effects of quenching-induced selection biases present in other jet measurements. The large statistics pp and Pb+Pb data delivered by the LHC in 2015 allow for a detailed study of photon-tagged jet quenching effects, such as the overall parton energy loss and modified structure of the component of the shower which remains correlated with the initial parton direction (e.g. in cone). In this proceeding, photon-tagged measurements... https://escholarship.org/uc/item/7qd7z6pc Wed, 30 Sep 2026 00:00:00 +0000 Perepelitsa, Dennis V Collaboration, ATLAS https://escholarship.org/uc/item/78b970xq A measurement of novel event shapes quantifying the isotropy of collider events is performed in 140 fb−1 of proton-proton collisions with s$$ \sqrt{s} $$ = 13 TeV centre-of-mass energy recorded with the ATLAS detector at CERN’s Large Hadron Collider. These event shapes are defined as the Wasserstein distance between collider events and isotropic reference geometries. This distance is evaluated by solving optimal transport problems, using the ‘Energy-Mover’s Distance’. Isotropic references with cylindrical and circular symmetries are studied, to probe the symmetries of interest at hadron colliders. The novel event-shape observables defined in this way are infrared- and collinear-safe, have improved dynamic range and have greater sensitivity to isotropic radiation patterns than other event shapes. The measured event-shape variables are corrected for detector effects, and presented in inclusive bins of jet multiplicity and the scalar sum of the two leading jets’ transverse momenta.... https://escholarship.org/uc/item/78b970xq Wed, 30 Sep 2026 00:00:00 +0000 Aad, G Abbott, B Abbott, DC Abeling, K Abidi, SH Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Abusleme Hoffman, AC Acharya, BS Adam Bourdarios, C Adamczyk, L Adamek, L Addepalli, SV Adelman, J Adiguzel, A Adorni, S Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Aguilar-Saavedra, JA Ahmad, A Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Ait Tamlihat, M Aitbenchikh, B Aizenberg, I Akbiyik, M Åkesson, TPA Akimov, AV Al Khoury, K Alberghi, GL Albert, J Albicocco, P Alderweireldt, S Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, A Alfonsi, F Alhroob, M Ali, B Ali, S Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allendes Flores, CA Allport, PP Aloisio, A Alonso, F Alpigiani, C Alvarez Estevez, M Alviggi, MG Aly, M Amaral Coutinho, Y Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amor Dos Santos, SP Amos, KR Ananiev, V Anastopoulos, C Andeen, T Anders, JK Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Anthony, MT Antipov, E Antonelli, M Antrim, DJA Anulli, F Aoki, M Aoki, T Aparisi Pozo, JA Aparo, MA Aperio Bella, L Appelt, C Aranzabal, N Araujo Ferraz, V Arcangeletti, C Arce, ATH Arena, E https://escholarship.org/uc/item/7836t7bm A combination of searches for Higgs boson decays into a visible photon and a massless dark photon (H → γγd) is presented using 139 fb−1 of proton-proton collision data at a centre-of-mass energy of s$$ \sqrt{s} $$ = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The observed (expected) 95% confidence level upper limit on the Standard Model Higgs boson decay branching ratio is determined to be B$$ \mathcal{B} $$(H → γγd) &lt; 1.3% (1.5)%.

The observed (expected) 95% confidence level limit on the cross-section times branching ratio ranges from 16 fb (20 fb) for mH = 400 GeV to 1.0 fb (1.5 fb) for mH = 3 TeV.

The study profits from the large background suppression provided by the use of a new transformer-based algorithm for jet identification and the sharper mass and transverse momentum, p_{T}, resolution from a dedicated regression model.

The results are based on a dataset of 139 fb−1 of proton–proton collisions at a centre-of-mass energy of 13 TeV, recorded by the ATLAS detector at the Large Hadron Collider. The measured total Higgs boson production cross-section is 55.5−3.8+4.0$$ {55.5}_{-3.8}^{+4.0} $$ pb, consistent with the Standard Model prediction of 55.6 ± 2.5 pb.

This analysis is performed using 137 fb−1 of pp collision data collected between 2016–2018 during Run 2 of the Large Hadron Collider by the ATLAS detector. Displaced vertices are identified using two different secondary vertexing algorithms, including a novel “fuzzy” vertexing algorithm optimized for identifying displaced decays of heavy quarks. Separate searches are performed using each algorithm, and the expected Standard Model background is independently estimated for each search using a data-driven procedure. No significant excess is observed over the background in either case. The results are used to set 95% confidence-level limits on potential beyond-the-Standard Model physics that could produce this final state.

In this Letter the first measurements of quantum entanglement between spins in pairs of Z bosons are reported, using proton-proton collision data from the Large Hadron Collider (LHC) at center-of-mass energies of 13 and 13.6&nbsp;TeV, recorded with the ATLAS detector. Measurements of angular observables sensitive to ZZ^{*} spin-density-matrix elements in the H→ZZ^{*}→ℓ^{+}ℓ^{-}ℓ^{+}ℓ^{-} process yield coefficients C_{2,1,2,-1}=-0.71±0.45 and C_{2,2,2,-2}=0.08±0.44, consistent with their Standard Model predictions. A complementary hypothesis test using the full angular distribution, and relying on several Standard Model assumptions in the decays, provides substantially higher sensitivity to quantum correlations and disfavors the separable-state hypothesis at a significance of 4.7 standard deviations (expected 4.9σ) relative to the entangled Standard Model hypothesis.

Data-driven methods are used to estimate the background contributions in the search regions. No significant excesses are found and 95% CL lower limits are placed on the masses of charginos and τ-sleptons in the lifetime range 0.01–10 ns.

This search is strongly motivated by a dramatic increase of the production cross-section by up to an order of magnitude for the highest masses considered, thanks to the small increase of 0.6 TeV in centre-of-mass energy between Run 2 and Run 3. No significant excess above the Standard Model background is observed, and 95% CL upper limits are set on the production cross-section times branching ratio in several benchmark models, reaching a mass scale of 9.4 TeV.

The reconstructed tb invariant mass is used to search for a W′ boson decaying into a top quark and a bottom quark. The result is interpreted in terms of a W′ boson with purely right-handed or left-handed chirality in a mass range of 0.5–6 TeV. Different values for the coupling of the W′ boson to the top and bottom quarks are considered, taking into account interference with single-top-quark production in the s-channel.

The results are expressed as upper limits on the W′ → tb production cross-section times branching ratio as a function of the W′-boson mass and in the plane of the coupling vs the W′-boson mass. https://escholarship.org/uc/item/2w6443qh Wed, 30 Sep 2026 00:00:00 +0000 Aad, G Abbott, B Abeling, K Abicht, NJ Abidi, SH Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Abusleme Hoffman, AC Acharya, BS Adam Bourdarios, C Adamczyk, L Adamek, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Ahmad, A Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Aitbenchikh, B Aizenberg, I Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S 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, JF Allendes Flores, CA Allport, PP Aloisio, A Alonso, F Alpigiani, C Alvarez Estevez, M Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amor Dos Santos, SP Amos, KR Ananiev, V Anastopoulos, C Andeen, T Anders, JK Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Anthony, MT Antipov, E Antonelli, M Anulli, F Aoki, M Aoki, T Aparisi Pozo, JA Aparo, MA https://escholarship.org/uc/item/2252c90c This search, a type not previously performed at ATLAS, uses a comparison of the production cross sections for e + μ − and e − μ + pairs to constrain physics processes beyond the Standard Model. It uses 139 fb − 1 of proton–proton collision data recorded at s = 13 TeV at the LHC. Targeting sources of new physics which prefer final states containing e + μ − to e − μ + , the search contains two broad signal regions which are used to provide model-independent constraints on the ratio of cross sections at the 2% level. The search also has two special selections targeting supersymmetric models and leptoquark signatures. Observations using one of these selections are able to exclude, at 95% confidence level, singly produced smuons with masses up to 640GeV in a model in which the only other light sparticle is a neutralino when the R-parity-violating coupling λ 231 ′ is close to unity.

Novel search techniques based on continuous wavelet transforms are used to infer the frequency of periodic signals from the invariant mass spectra and neural network classifiers are used to enhance the sensitivity to periodic resonances.

The data were collected with the ATLAS detector during LHC Run 2 and correspond to an integrated luminosity of 139 fb−1 of proton-proton collisions at a centre-of-mass energy of s$$ \sqrt{s} $$ = 13 TeV. The analysis is motivated by an extended Minimal Supersymmetric Standard Model featuring a non-minimal flavour violation in the second- and third-generation squark sector. The top squark in this model has two possible decay modes, either t~1→cχ~10$$ {\tilde{t}}_1\to c{\overset{\sim }{\chi}}_1^0 $$ or t~1→tχ~10$$ {\tilde{t}}_1\to t{\overset{\sim }{\chi}}_1^0 $$, where the χ~10$$ {\overset{\sim }{\chi}}_1^0 $$ is undetected. The analysis is optimised assuming that both of the decay modes are equally probable, leading to the most likely final state of tc+ETmiss$$ tc+{E}_T^{\textrm{miss}} $$.

The measurement is made with tt¯$$ t\overline{t} $$ events from pp collision data corresponding to an integrated luminosity of 140 fb−1 at a centre-of-mass energy of 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. A value of:Vcb=50−14+11×10−3$$ \left|{V}_{cb}\right|=\left({50}_{-14}^{+11}\right)\times {10}^{-3} $$is measured, where the uncertainties have roughly equal contributions from the limited size of the data sample and from systematic effects. This is consistent with existing measurements made at much lower energy scales in B hadron decays. While the sensitivity does not yet rival that of previous determinations, this novel approach probes a very different physical situation, namely the rare hadronic t→bb¯c$$ t\to b\overline{b}c $$ decay at high momentum-transfer, rather than semileptonic B decays at low momentum-transfer. https://escholarship.org/uc/item/1066f0pc Wed, 30 Sep 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 Ahmad, A Ahmadov, F Ahuja, S Ahuja, S Ai, X Aielli, G Aikot, A Ait Tamlihat, M Åkesson, TPA Akiyama, D Akolkar, NN Aktas, S Alberghi, GL Albert, J Alberti, U Albicocco, P 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 Almazan, ER Aloisio, A Alonso, F Alpigiani, C Alvarez Fernandez, A Alves Cardoso, M Alviggi, MG Aly, M Amaral Coutinho, Y Amelung, C Amerl, M Amezza, T Amini, B Amirie, K Amirkhanov, A 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 Apyan, A Arampatzi, M Arbiol Val, SJ https://escholarship.org/uc/item/0wb846ht This Letter presents a measurement of prompt charged-particle production in proton-oxygen interactions at sqrt[s_{NN}]=9.62  TeV center-of-mass energy with the ATLAS detector, corresponding to 634  μb^{-1} of integrated luminosity. A total of 246×10^{6} selected events have at least one track with transverse momentum p_{T}&gt;500  MeV and pseudorapidity |η|&lt;2.5. The measured fiducial proton-oxygen cross section is σ_{fid.}^{pO}=396±6(exp.)±9(lumi.)  mb and the extrapolated inelastic proton-air cross section is σ_{inel.}^{p+air}=406±6(exp.)±9(lumi.)±28(th.)  mb. Measurements of charged-particle multiplicity, p_{T}, and η distributions are an order-of-magnitude more precise than differences between hadronic-interaction models.
