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 outlines the ATLAS experiment's ongoing strategies to evaluate and mitigate the environmental impact of its massive, globally distributed computing infrastructure in preparation for the significantly increased resource demands of the High-Luminosity LHC era.
This paper presents a 63-day cosmic-ray scattering experiment using Resistive Plate Chambers to simultaneously measure secondary cosmic-ray composition with high precision and establish stringent constraints on muon-philic dark matter scattering cross-sections.
This paper proposes that a hypothetical color-octet, electroweak-singlet scalar particle () could explain a excess in CMS 4-jet data at a dijet mass of approximately 0.95 TeV, with a complex scalar variant providing a better fit to the observed signal shape and rate than a real scalar.
This paper introduces and evaluates a new W-based neutrino energy estimator for liquid-argon time-projection chambers, demonstrating that while it offers superior robustness against modeling uncertainties and minimal bias in the transition region between scattering regimes, its slightly worse energy resolution under ideal conditions suggests a complementary role alongside more exclusive methods for future oscillation analyses.
This paper presents a precision Standard Model analysis and new physics projections for the radiative decay at the LHC, demonstrating its potential to measure the branching ratio with sub-percentage accuracy and to probe axion-like particles and anomalous gauge bosons with enhanced sensitivity down to couplings of .
This paper demonstrates for the first time that neural simulation-based inference (NSBI) can effectively constrain proton parton distribution functions using high-dimensional, unbinned LHC data, achieving significantly improved precision over traditional binned analyses by fully exploiting statistical power and reducing reliance on coarse uncertainty approximations.
This paper presents a statistical framework that models quasiparticle dynamics following particle impacts to distinguish recombination and trapping processes, enabling the use of superconducting transmon qubits as energy-resolving detectors for reconstructing particle impact locations and energies.
This paper proposes and evaluates the experimental feasibility of the first dedicated measurement of transverse antiproton polarization in proton-nucleus collisions at CERN, utilizing left-right asymmetry in elastic scattering to probe the spin structure of the antinucleon-nucleon interaction.
This paper presents a proof-of-principle lattice QCD calculation of the charged kaon's electric polarizability using a four-point function approach on Wilson quenched lattices, yielding a value of and demonstrating the framework's applicability to strange mesons for future precision studies.
The BM@N experiment at JINR measured transverse momentum spectra and rapidity distributions of hyperons produced in carbon-nucleus collisions at 4.0A and 4.5A GeV, comparing the results with various theoretical transport models and existing experimental data.
