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 a study on optimizing the time resolution of Cherenkov-based Time-of-Flight detectors using thin high-refractive-index radiators coupled to Silicon Photomultiplier arrays, validating the design through detailed Monte Carlo simulations and beam test results.
This paper presents the development and validation of a high-precision Cherenkov-based Time-of-Flight detector using high-refractive-index radiators and Silicon Photomultipliers, which achieved a system-level time resolution better than 33.2 ps and 100% detection efficiency through rigorous optimization and CERN beam tests.
This paper demonstrates that AI agents, specifically Claude Code within a "Just Furnish Context" framework, can autonomously execute the entire high energy physics analysis pipeline—from data processing and statistical inference to paper drafting—to produce both established and novel results, suggesting the community must adapt its training and workflows to leverage these capabilities for enhanced scientific discovery.
This paper reports measurements of charged kaon and proton multiplicities in semi-inclusive deep-inelastic scattering at Jefferson Lab, revealing that while kaon data aligns with DSS fragmentation functions for but underpredicts , proton-to-pion ratios significantly exceed TMD predictions at low yet decrease at higher in agreement with Lund Monte Carlo models, with no significant differences observed between proton and deuteron targets.
This white paper introduces a novel, mobile deep-ocean neutrino detector prototype designed to significantly reduce crustal background noise, enabling the first direct measurements of mantle geoneutrinos to constrain Earth's radiogenic heat production and geochemical composition.
Using a novel quantum entanglement-based approach on 190 million events, the Belle II collaboration reports the first measurement of mixing-induced CP violation in decays, achieving unprecedented precision that significantly tightens constraints on the quark-mixing phase with far less data than previously thought necessary.
This paper investigates whether the next-generation helioscope IAXO can distinguish between signals from single versus multiple axion species by analyzing spectral signatures of axion flavor oscillations and mapping detection prospects in multi-axion parameter spaces.
This paper demonstrates that CPT violation can mimic the CP-violating phase in long-baseline neutrino experiments, potentially obscuring true measurements, and proposes using atmospheric neutrino data from IceCube and KM3NeT to constrain such violations and ensure unambiguous CP phase determination.
This paper investigates composite neutrino models where an inverse seesaw mechanism with anomalous scaling dimensions suppresses light neutrino masses while generating enhanced electromagnetic dipole moments, leading to distinctive single- and multi-photon radiative signatures in MiniBooNE and MINERvA experiments that serve as a novel probe of partial compositeness.
This review highlights recent breakthroughs in extending uncertainty-quantified *ab initio* nuclear theory to heavy and complex nuclei, demonstrating how these advances significantly reduce nuclear-physics uncertainties in interpreting dark matter direct detection experiments.
