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 reveals that laser-driven shock compression of FeO induces an anomalous 7–10% isostructural volume collapse around 60 GPa due to a high-spin to low-spin electronic transition, a phenomenon absent in static compression experiments despite the material retaining its rocksalt structure up to the melting point at 191 GPa.
This paper proposes a self-supervised sparse ViT framework that leverages masked autoencoding and relational objectives to learn reusable representations from heterogeneous neutrino detector data, significantly improving reconstruction performance and data efficiency for energy-frontier experiments like FASERCal while demonstrating strong transferability across diverse detector technologies.
The MINERvA collaboration reports the first measurement of inclusive charged-current cross sections on carbon, hydrocarbon, iron, and lead at a mean energy of GeV, revealing significant discrepancies between experimental data and current neutrino interaction models, particularly regarding nuclear effects at low antimuon transverse momentum.
This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
This paper presents recent ALICE measurements from July 2025 LHC runs involving proton-oxygen, oxygen-oxygen, and neon-neon collisions, detailing charged-particle pseudorapidity densities, flow coefficients, and neutral pion suppression to advance the understanding of particle production and collective phenomena in small collision systems.
Using LHC Run 2 central exclusive diphoton production data, this study constrains the existence of magnetic monopoles and high-electric-charge objects by analyzing their virtual contributions to light-by-light scattering within effective field theories and Born-Infeld scenarios, excluding masses up to several tens of TeV.
This paper proposes a novel laboratory test of gravity that combines seismic-wave measurements with cosmic-ray muon detections to constrain quantum-gravity corrections to the Debye model while eliminating density-related uncertainties through muon tomography.
This paper demonstrates that silver-zeolite (Ag-ETS-10) outperforms activated charcoal by three orders of magnitude in radon removal at room temperature, establishing it as a highly promising adsorbent for reducing background contamination in dark matter and neutrino experiments.
This paper calculates next-to-leading order nuclear matrix elements for two-neutrino double-beta decay to excited states in key isotopes using the nuclear shell model, finding that while NLO corrections are typically small, they can become significant due to leading-order cancellations, and that nuclear deformation and seniority structure critically influence the predicted half-lives.
This paper presents preliminary results for the first radial excitations of -wave charmonia in the 3.85–3.95 GeV region, calculated using the Resonance-Spectrum Expansion with full OZI-allowed decay channels and a generalized model to explain the disparate mass patterns observed in unquenched scenarios compared to static quark models.
