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 review synthesizes the current experimental landscape for measuring the tau lepton's anomalous magnetic moment, contrasting the complementary strengths of Ultra-Peripheral Heavy-Ion Collisions and proton-proton data at the LHC with the superior precision prospects of future lepton colliders like Belle II and FCC-ee.
This paper reports the inclusive differential production cross-section of forward photons in proton-proton collisions at = 510 GeV measured by the RHICf experiment, finding that the results are consistent with Feynman scaling and various hadronic interaction models despite some predicted energy dependencies.
This paper proposes and evaluates a parametrized quantum circuit-based anomaly detection algorithm for high-energy physics, demonstrating its feasibility on both simulations and NISQ hardware while acknowledging that current noise levels prevent it from outperforming classical deep neural networks.
This paper investigates the potential of the DUNE near detector to probe a five-dimensional gauge extension of the Standard Model, which addresses the muon anomaly, by analyzing elastic neutrino-electron scattering data to explore MeV-scale parameter spaces and interference effects between multiple massive gauge bosons.
The paper introduces \texttt{IAFormer}, a novel Transformer-based architecture that leverages boost-invariant pairwise quantities and a dynamic sparse "differential attention" mechanism to achieve state-of-the-art classification performance on collider data with over an order of magnitude greater computational efficiency than existing Particle Transformer models.
This paper critiques a recent study (arXiv:2507.07180) by arguing that its proposed ad-hoc symmetrization of Dirac neutrino amplitudes lacks physical justification and incorrectly violates lepton number conservation within the Standard Model.
This paper proposes using the one-point energy correlator (OPEC) in transversely polarized proton-proton collisions as a novel, infrared-and-collinear safe method to probe the nucleon's transversity distribution with a clean angular asymmetry over a wider kinematic range than traditional hadron transverse momentum measurements.
Using 13 TeV proton-proton collision data from the LHCb experiment, researchers measured the branching fraction of the decay with twice the precision of previous results, finding it consistent with Standard Model predictions and providing a stringent test of lepton flavour universality in transitions.
This paper demonstrates that a minimally reconfigured version of CERN's existing NA62 experiment, operating in a future ECN3 beam-dump facility with an optimized geometric setup, can achieve highly competitive sensitivity for detecting feebly interacting particles in the MeV to GeV mass range immediately upon beam availability.
The paper proposes DMRadio-Core, a novel experimental design utilizing a segmented solenoid and external LC resonators to significantly reduce the required magnetic energy while maintaining sensitivity, thereby enabling a near-term search for GUT-scale QCD axions in the 30–200 MHz range with a scalable path to lower frequencies.
