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 develops and validates a model for predicting the dark count rate of photomultiplier tubes by incorporating the Richardson-Dushman equation and Schottky effect, demonstrating that while temperature significantly influences thermionic emission, external electric fields up to 1100 V cause a relatively minor increase in dark counts.
This paper presents an AI-assisted framework for local infrared subtraction that combines EFT matching with neural network or analytic constructions to enable efficient, slicing-parameter-free higher-order QCD calculations, successfully reconstructing NLO results for multi-jet production and demonstrating feasibility on modest hardware.
This paper utilizes the Standard Model Effective Field Theory (SMEFT) to demonstrate how current and future electric dipole moment measurements, particularly of the proton, provide highly sensitive and complementary constraints on CP-violating top-quark interactions by accounting for complex multi-loop effects and renormalization-group evolution.
This paper demonstrates that the breakdown of fixed-order perturbation theory in high-energy LHC processes, caused by large logarithms of , is resolved by resumming these logarithms, thereby providing accurate predictions for +dijet production that match recent ATLAS measurements.
Using 7.33 fb⁻¹ of collision data collected by the BESIII detector, this study measures the inclusive branching fractions of and decays with significantly improved precision compared to previous CLEO results.
This paper introduces two hybrid techniques, particularly recommending the "Latent Categories" approach, that significantly reduce the computational cost of neural simulation-based inference while maintaining robustness and reliability guarantees for applications ranging from offline analyses to future trigger-level scenarios.
This paper proposes and validates through full Monte Carlo simulation effective kinematic variables in the rest frame of the top-quark and mediator decay cluster to search for, classify, and measure the masses of dark matter mediators in single top quark production processes at the LHC.
This paper compares spin correlation predictions from toponium bound state models and non-relativistic QCD resummation against LHC data, demonstrating that while toponium scenarios yield drastically enhanced correlations, the resummation effect significantly improves agreement with experimental distributions and cross-section measurements, suggesting a viable path to characterizing the observed excess.
This paper demonstrates that the Future Circular Collider (FCC-ee) can leverage Tera- statistics and modern jet flavor reconstruction to study exclusive four-body decays as precision probes of flavor-specific new physics, offering direct multi-TeV sensitivity to contact interactions and bridging the electroweak and flavor programs.
This document provides the U.S. Muon Collider Collaboration's input to the SCAC Facilities Subcommittee, outlining the scientific case, necessary R&D roadmap, and strategic relevance of a future Muon Collider to U.S. facility planning for 2026–2036 while emphasizing workforce development and international synergies.
