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 introduces a model-agnostic graph autoencoder framework that leverages sparse graph constructions and subjet clustering to enhance anomaly detection performance and interpretability in high-dimensional LHC data.
This paper presents the design, fabrication, and performance evaluation of a full-scale muon scattering tomography system utilizing four layers of high-precision plastic-scintillator detectors to enable non-destructive imaging of high-Z materials for security and nuclear monitoring applications.
This paper introduces IJazZ2.0, a novel analytical likelihood maximization method that utilizes automatic differentiation to efficiently and accurately determine lepton and photon energy scale and resolution corrections from Drell-Yan events, offering superior computational performance and numerical stability compared to conventional techniques.
Using the two-point QCD sum rule approach, this study analyzes the low-lying spin- spectrum and identifies the newly observed resonance as the first radial () excitation, as its calculated mass of aligns with the experimental value reported by BESIII.
This study demonstrates that quantum annealing can effectively solve the combinatorial optimization problems inherent in particle track reconstruction for strip-type detectors, achieving resolution comparable to classical Kalman methods while providing a practical foundation for hybrid quantum-classical approaches in complex environments.
Using proton-proton collision data collected by the LHCb experiment, this paper reports the first search for the radiative leptonic decays and at a hadron collider, finding no evidence for these processes and setting upper limits on their branching fractions.
Using 13.6 TeV proton-proton collision data from the ATLAS experiment, researchers measured the production of two longitudinally polarized bosons and, by combining these results with previous 13 TeV data, achieved the first observation of this process with a significance of 6.5 standard deviations.
This paper reports the first demonstration of single-shot high-energy radiography using a multi-GeV laser-wakefield-accelerated beam of muons, pions, and neutrons, successfully imaging objects through dense shielding and confirming the muon-dominated, highly penetrative nature of the source.
Using 140 fb⁻¹ of 13 TeV proton-proton collision data collected by the ATLAS detector, this paper presents measurements of high-mass production and sets constraints on lepton-flavour-universality-violating effective field theory operators, finding no significant deviations from Standard Model predictions.
Using 140 fb of 13 TeV proton-proton collision data collected by the ATLAS detector, this paper presents the first measurement of differential cross-sections for production in the dilepton channel at the particle level, providing crucial constraints on the modeling of top-quark processes and their interference effects.
