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 the first experimental search for the -naturalness tower of neutrinos using a global analysis of public data, which successfully rules out the benchmark scenario of gauge and gravitational unification at the GUT scale () for Majorana neutrinos with a fine-tuning parameter .
This paper presents a comprehensive study of timing resolution in plastic scintillator detectors using wavelength-shifting fibers and silicon photomultipliers, combining a semi-analytical model with toy Monte Carlo and full Geant4 simulations to validate predictions and generate quantitative design maps for optimizing detector performance across various materials, components, and configurations.
This paper presents a unified Khuri-Treiman formalism that combines production effects and final-state interactions to analyze COMPASS's "freed-isobar" data on the decay, successfully extracting the relative strengths and phases of production mechanisms to enable a future precise determination of the pole position.
This paper outlines the comprehensive, standardized quality control framework implemented across international institutes to validate the mechanical and electrical conformity of approximately 18,000 ATLAS18 silicon strip sensors for the HL-LHC ITk upgrade, reporting a 91% acceptance rate and detailing key performance metrics and anomaly case studies from over 590 production batches.
The LHCb experiment has successfully implemented a fast, GPU-accelerated Kalman filter using analytical parameterizations to perform full track fitting at the 30 MHz collision rate, achieving a two-fold improvement in invariant mass resolution and significantly enhanced background rejection with only a 2% increase in processing time.
This paper computes the relativistic correction to the high-energy resummed coefficient function for exclusive heavy quarkonium photoproduction, finding that while the correction itself is negligible at the physical mass scale, it significantly improves prediction robustness by partially canceling the factorization scale dependence of the leading-order relativistic correction.
This paper evaluates various hadronic energy reconstruction methods for the SDHCAL within the ILD detector using the APRIL Particle Flow Algorithm, finding that split and polynomial regression techniques offer the best balance of linearity and resolution while highlighting the potential of integrating precise timing information to further reduce PFA confusion.
This paper introduces radiative corrections within an effective field theory framework for neutral-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these corrections are comparable in magnitude to strange quark contributions and yield excellent agreement with BNL E734 and MiniBooNE experimental data.
This study investigates the bulk damage in high-oxygen and varying-resistivity -in- silicon diodes subjected to high-dose gamma irradiation, revealing a linear increase in leakage current, a non-monotonic evolution of full depletion voltage driven by acceptor removal, and a notable absence of annealing effects on electrical characteristics.
This paper calculates substantial and positive next-to-next-to-leading order (NNLO) QCD corrections for pion- and kaon-induced exclusive Drell-Yan processes within the generalized parton distribution framework, establishing the necessity of including these higher-order effects for reliable theoretical predictions to match future J-PARC experimental data.
