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 study demonstrates the feasibility of identifying and discriminating between gamma and neutron sources in Water Cherenkov Detectors by integrating statistical energy thresholding with an ensemble machine learning model, achieving an accuracy of 0.816 for enhanced radiation identification in nuclear security applications.
This paper presents the first calculation of the threshold corrections to the inclusive -boson production cross-section by deriving complete quark form factors and constructing the soft-virtual cross-section, thereby significantly improving theoretical precision and reducing uncertainties for future collider programs.
This paper presents a consistent reanalysis of low-energy neutrino scattering data, combining coherent elastic neutrino-nucleus and neutrino-electron scattering measurements to determine the low-energy weak mixing angle as , thereby providing an independent precision test of the Standard Model that complements atomic parity violation results.
This paper calculates the inclusive weak branching fraction of the meson to be approximately using the optical theorem and heavy-quark expansion, revealing that pair annihilation (including significant neutral-current and - interference contributions) dominates over conventional single-charm decays.
This paper investigates neutrino transition polarizability within an inverse seesaw framework involving a light pseudoscalar that couples active neutrinos to heavy neutral leptons and photons, demonstrating how the resulting decay channels alter heavy neutrino lifetimes and identifying the enhanced sensitivity of displaced photon searches at facilities like DUNE, Belle II, LHCb, and FCC-ee.
This paper demonstrates that sequential simulation-based inference significantly improves the accuracy and calibration of likelihoods for extracting resonance masses and widths at the LHC by iteratively concentrating simulations on regions of interest, outperforming traditional single-round training methods.
This paper demonstrates that new gauge interactions, specifically through extensions like , , and , can significantly enhance the production of Heavy Neutral Leptons at forward LHC experiments (FASER, FASER, and their HL-LHC successors) via proton bremsstrahlung and Drell-Yan processes, thereby enabling the exploration of previously unaccessible parameter space and potentially reaching canonical seesaw predictions independent of the active-sterile mixing that governs their decays.
This paper demonstrates that foundation models trained on multi-modal data significantly outperform traditional methods in reconstructing charged particles and identifying them within Time Projection Chamber datasets, while also showing adaptability to diverse downstream physics tasks.
This paper demonstrates that naturally abundant chlorine in seawater significantly enhances the detection of electron antineutrinos via a distinctive delayed-coincidence signature, effectively doubling the discovery reach for core-collapse supernovae in deep-ocean neutrino telescopes.
This study demonstrates that University of South Dakota-grown germanium crystals can successfully achieve Neganov-Trofimov-Luke amplification in SuperCDMS-style detectors, provided that high-quality crystal growth is paired with the deposition of aluminum bias contacts to enable voltage-dependent energy gain.
