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.
This paper presents Simphony, a GPU-accelerated optical photon Monte Carlo tool that achieves a ~1000-fold speedup over Geant4 while maintaining subpercent accuracy in photon detection metrics, thereby enabling practical large-scale optical simulations for noble liquid detector development and machine learning applications.
Using QCD sum rules with six independent interpolating currents and including nonperturbative condensates up to dimension ten, this study predicts the mass of a compact hidden-charm hexaquark with quark content to be in the range of 3.94–4.41 GeV, providing a theoretical reference for future experimental searches.
Using LHCb data from proton-proton collisions at 13 TeV, this study demonstrates that associated + production in the forward region is dominated by multiparton interactions, yielding an effective cross-section of mb that provides new constraints on the proton's transverse spatial structure at small Bjorken-.
This paper presents recent measurements of Higgs boson properties, including its mass, width, and CP nature in various couplings, derived from proton-proton collision data at 13 TeV and 13.6 TeV collected by the ATLAS and CMS experiments.
This paper presents a comprehensive study of anomalous quartic gauge couplings in same-sign boson scattering at the LHC within the SM Effective Field Theory framework, demonstrating that combining angular asymmetries derived from polarization and spin correlations with conventional kinematic observables yields improved constraints on Wilson coefficients while ensuring unitarity safety.
This paper proposes the design of two dedicated long-lived particle (LLP) detectors, DELIGHT and FOREHUNT, for the Future Circular Collider (FCC) facility, featuring a novel shared transverse detector for both FCC-ee and FCC-hh runs to optimize costs and significantly enhance sensitivity to elusive new physics.
This paper analyzes recent electron and nuclear recoil data from XENONnT, PandaX-4T, and LUX-ZEPLIN to probe both Standard Model and Beyond the Standard Model physics, highlighting how xenon-based dark matter detectors can uniquely complement dedicated neutrino experiments by providing sensitivity to solar neutrino interactions and flavor-dependent new physics effects.
This paper investigates sub-GeV dark matter signatures from dark showers in strongly-interacting dark sectors, demonstrating that beam-dump experiments like SHiP could detect multiple displaced vertices in single events to reveal the dark sector's structure, while also evaluating current constraints from NA62 and BaBar and future sensitivities at Belle II.
Using 13 TeV proton-proton collision data corresponding to 5.4 fb⁻¹ of integrated luminosity, the LHCb experiment presents the first measurements of differential and total top- and antitop-quark production cross-sections and the top-quark charge asymmetry in the forward region, finding results consistent with next-to-leading-order Standard Model predictions.
This paper presents a model-independent analysis of HERA's exclusive coherent diffractive production data using artificial neural networks to predict differential cross-sections and extract a - and -dependent exponential slope by integrating HERA and LHC datasets.
