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 GlueX experiment's comprehensive research program for strangeness production, focusing on strange meson spectroscopy, spin dynamics in photoproduction, and hadronization studies, while providing an outlook for the upcoming high-statistics GlueX-II era.
This paper demonstrates that quantum-information-motivated observables, particularly the spin correlation measured as a function of visible invariant mass in dileptonic top-quark pair events at the High-Luminosity LHC, significantly enhance the sensitivity to invisible new physics and the discrimination of mediator couplings compared to traditional rate and kinematic analyses.
This paper presents the first measurement of the angle between jet axes in central Pb-Pb collisions at TeV, revealing a distribution narrowing that suggests quark-initiated jets survive the quark-gluon plasma more readily than gluon-initiated ones and favoring incoherent energy loss mechanisms over simple intra-jet broadening.
The paper introduces HyPER, a novel hypergraph-based neural network architecture that outperforms existing state-of-the-art techniques in reconstructing short-lived particles from complex collider events while demonstrating superior parameter efficiency.
The ALICE collaboration reports the first measurement of the nuclear modification factor for D-tagged charm jets in Pb-Pb collisions at TeV, observing a hint of reduced suppression compared to inclusive jets that supports the influence of both color-charge and dead-cone mass effects on in-medium energy loss, with the LIDO model providing the best description of the data.
This paper reports the first observation of distinctive baryon-meson grouping in anisotropic flow within high-multiplicity proton-proton and proton-lead collisions at the LHC, providing strong evidence for the formation of partonic flowing systems consistent with quark-gluon plasma in these smaller collision systems.
This paper reports on the azimuthal correlations between electrons from heavy-flavor hadron decays and associated charged particles in Pb–Pb collisions at TeV, revealing that the nuclear modification factor () for these heavy-flavor triggers is consistent with that of light-flavor and strange-particle triggers within uncertainties.
This paper presents the first measurements of K production in pp collisions at TeV as a function of event multiplicity, revealing a significant 7 suppression of the K/K yield ratio in high-multiplicity events that is well-described by the EPOS-LHC model without hadronic afterburners.
This paper presents the first high-precision femtoscopic measurements of -meson correlations in 13 TeV pp collisions at the LHC, revealing repulsive and shallow attractive interactions for -K and - systems respectively while characterizing the and resonances to constrain theoretical models of hadron dynamics.
This paper presents the first measurement of the proton- femtoscopic correlation function in high-multiplicity pp collisions at TeV using the ALICE detector, enabling the discrimination of N- interaction models and the first determination of p- scattering parameters.
