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 fast, high-fidelity generative model based on score-driven diffusion and the Point-Edge Transformer architecture that successfully simulates realistic, high-multiplicity heavy-ion collision events through a two-stage training strategy, demonstrating its potential to replace computationally intensive traditional simulations.
This paper proposes a source-informed event selection strategy for neutrino telescopes that preferentially retains events aligned with known candidate sources, demonstrating that this approach can improve median point source sensitivity by factors of 2–3 with only modest computational overhead.
This paper evaluates solar neutrino flux fluctuations caused by solar gravity modes, concluding that while detecting individual modes via time-varying flux changes is currently impossible due to their small amplitude, the non-time-varying component could produce a measurable, activity-cycle-dependent net increase in the mean neutrino flux that offers a potential method for constraining g-mode excitation theories.
Using high-resolution XRISM/Resolve spectroscopy combined with NuSTAR data and plasma modeling, this study characterizes the plasma dynamics of the AM Herculis accretion column by resolving intrinsic Fe line broadening to reveal velocity and temperature gradients, confirming resonance anisotropy, and deriving a self-consistent shock temperature of 24.0 keV and density of cm to constrain the column's geometry.
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.
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 extends the semileptonic sum rule to include strange baryon and meson decays, quantifies the impact of SU(3) symmetry breaking to confirm it remains within experimental uncertainties, and proposes new predictive sum rules to rigorously test the consistency of processes.
