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 evaluates the viability of , , and discrete flavour symmetries by incorporating the first JUNO measurement of into global neutrino oscillation data, revealing that the number of compatible mixing pattern cases is reduced from five to three for normal ordering and from four to two for inverted ordering at the confidence level.
This paper introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This paper enhances the explainability of quark-gluon jet taggers by identifying key latent features, evaluating the limitations of Shapley values in correlated inputs, and employing symbolic regression to derive compact formulas that approximate the tagger's output.
This paper presents a prediction method for PMT afterpulse rates in the SUBMET experiment that achieves approximately 20% precision, thereby enhancing the reliability of background predictions for the search of millicharged particles.
Using a dataset of 428 fb collected by the Belle II experiment, researchers measured the time- and phase-space-integrated asymmetry in decays to be , which represents the most precise result to date and is consistent with conservation.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
Using 138 fb of 13 TeV proton-proton collision data collected by the CMS experiment, this study characterizes the quantum state of top quark-antiquark pairs by measuring spin correlations in the beam and helicity bases to decompose the system into Bell and spin eigenstates and evaluate properties like purity, entropy, and entanglement, with all results aligning with Standard Model predictions.
This paper implements next-to-leading order QCD corrections for the process within the ggxy framework, augmented with leptonic decays and an interface to POWHEG to enable parton shower simulations using Pythia.
This paper introduces a differentiable, multi-scale Effective Field Theory framework that integrates renormalization-group evolution, matching, and experimental constraints to enable efficient gradient-based inference in large parameter spaces, as demonstrated through comprehensive 374-parameter SMEFT analyses.
This paper extends previous bounds on the axion-photon coupling by over an order of magnitude using the SACLA X-ray free electron laser and the Borrmann effect in Laue crystals, achieving the most stringent laboratory constraints to date for QCD axions in the 3.46–3.48 keV mass range.
