Hep-Ex explores the fascinating intersection where particle physics meets experimental reality. This field investigates how scientists build massive detectors and accelerate particles to test the fundamental laws of nature, turning abstract theories into measurable data. It is the rigorous process of searching for new particles or forces that could reshape our understanding of the universe, often requiring years of collaboration and engineering.
At Gist.Science, we ensure these discoveries become accessible to everyone. We process every new preprint in this category directly from arXiv, generating both plain-language explanations for curious readers and detailed technical summaries for specialists. Our goal is to bridge the gap between complex experimental results and public understanding without losing scientific nuance.
Below are the latest papers in Hep-Ex, freshly summarized and ready for you to explore.
Using 301 fb of proton-proton collision data at 13 and 13.6 TeV collected by the ATLAS detector, this study reports the first evidence of Higgs boson inclusive production at high transverse momentum ( GeV) decaying to a pair, achieving a 3.8 observed significance through advanced jet identification and regression techniques.
The ALICE Collaboration reports the first measurements of the average transverse-momentum fraction for strange hadrons in 13 TeV pp collisions, revealing distinct production trends for mesons and baryons that current Monte Carlo models fail to describe.
This paper presents six global analyses of generalized parton distributions (GPDs) at zero skewness using various modern PDF sets and factorization scales, demonstrating that NNPDF40 at NLO provides the best fit to elastic electron scattering data while revealing moderate sensitivity to PDF inputs and perturbative orders.
This paper proposes that the global hyperon polarization observed in low-energy heavy-ion collisions can be partially explained (accounting for ~23% of the signal) by a mechanism linking it to long-standing transverse polarization phenomena via the alignment of production and reaction planes driven by directed flow, rather than solely by quark-gluon plasma vorticity.
This paper employs the QCD sum rule approach with three distinct interpolating currents to predict the masses and current coupling constants of fully heavy pentaquark candidates containing three charm and two bottom quarks () or three bottom and two charm quarks () with spin-parity .
Using 138 fb of 13 TeV proton-proton collision data collected by the CMS experiment, this paper presents the first unfolded double-differential cross-section measurements of boosted W+jets events to extract a W boson mass of 80.83 0.55 GeV, achieving the smallest uncertainty to date for an all-jets final state at a hadron collider.
Using 164 fb⁻¹ of 13.6 TeV proton-proton collision data collected by the ATLAS detector, this study employs matrix element-based observables and angular distributions to constrain CP-odd couplings and probe Higgs boson interactions with polarized vector bosons in vector-boson fusion events, confirming Standard Model predictions while achieving improved sensitivity through a new neural network classification algorithm.
Using 140 fb of 13 TeV proton-proton collision data from the ATLAS detector, this paper presents a combined analysis of Higgs boson interactions with vector bosons across multiple decay channels, finding no evidence of CP violation and establishing the most stringent constraints to date on relevant CP-violating SMEFT Wilson coefficients, including simultaneous limits on three coefficients for the first time.
This paper proposes a generalized Georgi-Machacek Model without custodial symmetry to explain recent LHC excesses in vector-boson fusion channels by allowing mass splitting among new Higgs bosons, thereby accommodating observed signals in , $WZ$, and di-photon production while satisfying experimental constraints.
This study utilizes microwave whispering gallery mode analysis to characterize the temperature-dependent biaxial dielectric permittivity and loss tangents of single-crystal calcium tungstate from room temperature down to 4 K, revealing improved cryogenic performance and identifying a magnetic loss channel relevant to quantum and bolometric applications.
