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 demonstrates the first successful application of an online, charge-based data selection algorithm in a liquid argon time projection chamber using MicroBooNE data, providing a proof-of-principle for real-time signal preservation in future large-scale experiments like DUNE.
The paper proposes two cost-effective, medium-baseline neutrino experiments—SINE (a surface scintillator detector) and UNDINE (a submerged water Cherenkov detector)—to study LHC-produced neutrinos and constrain neutrino cross sections and cosmic-ray physics.
This paper demonstrates that a Graph Neural Network (GNN) outperforms an XGBoost classifier in enhancing the sensitivity of searches at 13.6 TeV, significantly improving the expected upper limits on the double Higgs production cross-section and the Higgs boson self-coupling () compared to current ATLAS results.
This paper demonstrates that future electron-positron colliders like the FCC-ee can significantly outperform the LHC in detecting displaced signals from heavy Majorana neutrinos, potentially probing Left-Right symmetric model scales in the multi-TeV regime through various production channels and advanced vertexing techniques.
By analyzing the Lund jet plane of high-energy jets in PbPb collisions compared to pp collisions, this study finds no significant difference in the angular distribution of high- emissions, suggesting that these early parton emissions occur before the jet interacts substantially with the quark-gluon plasma.
Using a sample of approximately one billion events collected by the BESIII detector, this paper reports the first observation of the decay and provides its measured branching fractions considering both constructive and destructive interference scenarios.
This paper demonstrates that a light invisible resonance (with a mass of approximately $2.1$ GeV) provides a compelling explanation for the excess observed by Belle II in decays, with both Bayesian and frequentist analyses favoring this new-physics hypothesis over the Standard Model.
This paper presents a combined measurement from the Belle and Belle II experiments of the rare leptonic decay , yielding a branching fraction of and providing the most precise search for this process to date.
Using the QCD sum rule method, this paper investigates the properties of two heavy-quark hadronic molecules, and , predicting their masses and relatively broad decay widths to demonstrate their instability against dissociation.
This paper presents the first complete NNNLO QCD corrections to the top-quark decay width and -helicity fractions, providing high-precision theoretical predictions that meet the accuracy requirements of future particle colliders.
