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.
The 2026 Global Report on Data Preservation in High Energy Physics highlights significant advancements in legacy data revival and the integration of AI-driven automation, while underscoring the critical need for sustained funding and institutional support to ensure the long-term sustainability of open science and FAIR data principles.
This paper employs a hybrid transverse momentum dependent approach to confirm the universality of the Collins function by successfully describing STAR proton-proton collision data and subsequently provides leading-order predictions for Electron-Ion Collider kinematics, demonstrating that quasireal photon exchange effects, while sizable, do not hinder the clear extraction of the transversity distribution and its sea-quark component in lepton-proton collisions.
This paper presents new analytical expressions and predictions for double quarkonium production in unpolarized and polarized hadronic collisions at fixed-target experiments, utilizing transverse momentum dependent factorization combined with the Color-Singlet Model to describe angular structures, cross sections, and transverse single-spin asymmetries for current and future CERN and LHC facilities.
This paper presents the first calculation of single inclusive hadron and jet production at large transverse momentum in lepton-hadron scattering using a joint QCD+QED factorization framework, which introduces universal lepton distribution functions with combined evolution kernels and provides predictions for experiments at Jefferson Lab and the future Electron-Ion Collider.
This paper introduces MAIA, a new all-silicon detector concept optimized for a 10 TeV muon collider that demonstrates high reconstruction efficiencies for energetic particles even under realistic beam-induced background conditions.
This paper employs the Born--Oppenheimer effective field theory to analyze hidden-charm pentaquarks discovered by LHCb, identifying them as bound states in specific potentials, predicting their spin assignments and decay patterns, and providing the first theoretical estimates for adjoint baryon masses to be verified by future lattice QCD studies.
This paper presents a novel lead-glass calorimeter that utilizes beam dump leakage to measure high-energy electron and photon flux with approximately 10% precision, few-percent accuracy, and micrometer-level position resolution, as demonstrated by a prototype at the DESY FLASHForward experiment.
This paper employs the QCD sum rule method to calculate the form factors and decay widths for the semileptonic weak transition , providing theoretical benchmarks for future experimental studies of excited heavy baryon dynamics.
This paper presents and evaluates machine-learning-based anomaly detection methods for model-independent searches for new physics in dijet final states using 13 TeV proton-proton collision data from the CMS experiment, demonstrating their effectiveness in identifying anomalous jets and boosted top quarks without relying on specific theoretical models.
This paper presents a model-independent search for light charged Higgs bosons (110–165 GeV) produced via rare top decays () followed by the off-shell decay , establishing new constraints on this previously unconstrained channel by reinterpreting ATLAS dileptonic measurements and demonstrating its competitive sensitivity in specific two-Higgs-doublet scenarios near the top-quark mass threshold.
