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 investigates exclusive semileptonic and nonleptonic decays using a relativistic quark model to calculate form factors and predict branching fractions on the order of to , which are then compared with existing theoretical predictions and experimental upper bounds.
This paper presents the first systematic investigation of heavy-flavor fragmentation into fully charmed or bottomed tetraquarks across scalar, axial vector, and tensor configurations using a nonrelativistic QCD framework, while propagating uncertainties from long-distance matrix elements to advance the understanding of exotic matter formation.
This paper reviews recent inclusive and differential cross-section measurements by the ATLAS and CMS collaborations, highlighting investigations into off-shell effects, Monte Carlo modeling, and the observation of quasi-bound states near the production threshold for indirect Yukawa coupling extraction.
Using 62 fb of proton-proton collision data at = 13.6 TeV collected by the CMS detector, this paper presents the first search for Higgs boson pair production in the decay channel with two leptons, finding results consistent with the Standard Model and setting an upper limit of 12.0 times the predicted cross section at 95% confidence level.
This paper describes the construction and key design features of a new large-acceptance forward-angle magnetic spectrometer at Jefferson Lab, which utilizes a horizontal slit opening through the magnet yoke to achieve a 70 msr solid angle while employing magnetic shielding and correcting magnets to minimize beamline interference.
This paper proposes a Template-Adapted Mixture Model that leverages multiple biased simulations to perform robust, data-driven parameter inference for signal fraction estimation, effectively mitigating simulation-data mismodeling in complex particle physics analyses.
This paper presents a locally deployed, cost-effective Retrieval-Augmented Generation (RAG) system utilizing an open-source LLaMA model and an in-house arXiv database to provide secure, domain-specific question answering for the Electron-Ion Collider (EIC) experiment while ensuring data privacy.
This review extends the study of inclusive vector quarkonium production at the LHC using the JETHAD method and a hybrid NLL/NLO factorization approach, demonstrating enhanced stability in forward rapidity regions and offering a unique opportunity for precision high-energy QCD studies and resolving the quarkonium production puzzle.
This paper reviews the semi-inclusive hadroproduction of neutral hidden-flavor tetraquarks at the HL-LHC using the JETHAD framework and novel TQHL1.0 fragmentation functions, demonstrating that high-energy observables for these exotic states remain stable under radiative corrections and providing a crucial link between QCD resummation techniques and exotic matter research.
This paper reviews and extends the application of the JETHAD method to analyze the NLL/NLO+ behavior of light and heavy hadron production in forward and far-forward rapidity ranges, demonstrating the stabilization of semi-inclusive heavy hadron detections against higher-order corrections and exploring kinematic regions accessible at current LHC experiments and future Forward Physics Facilities.
