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 presents a sensitivity study demonstrating that solar neutrino experiments can detect heavy sterile neutrinos in the MeV mass range by combining complementary detection methods for decay products ( pairs or ), thereby extending the observable parameter space for mixing angles and masses.
This paper presents optimization studies for a cosmic muon tomography scanner designed for cargo border control, utilizing both a differentiable programming approach enhanced with Bayesian Optimization and detailed GEANT4 simulations to refine detector configurations and improve material discrimination.
Using 133 fb of 13 TeV proton-proton collision data, the ATLAS collaboration performed a search for Standard Model Higgs bosons produced via vector-boson fusion in association with a high-energy photon and decaying to , employing improved analysis techniques to measure a signal strength of with an observed significance of 0.3 standard deviations, consistent with the background-only hypothesis.
The paper introduces E-PCN, an explainable graph neural network that integrates four distinct kinematic feature-weighted graph representations to achieve state-of-the-art jet classification performance on the JetClass dataset while identifying angular separation and transverse momentum as the dominant factors driving its decisions.
Using QCD sum rules with dimension-12 condensates, this study calculates the mass spectra of hexaquark states and finds that the ground states lie around 5.8 GeV, consistent with BESIII's non-observation of a near-threshold bound state, while also predicting masses for hidden-bottom candidates.
This paper introduces OmniMol, a state-of-the-art machine-learned interatomic potential for small molecules that leverages a Point-Edge Transformer architecture and knowledge transfer from high-energy physics to achieve excellent performance with minimal fine-tuning and uniquely fast inference.
This paper demonstrates that CP violation in the decay induced by neutral kaon mixing is a second-order weak interaction effect estimated at the level, rendering it negligible compared to current experimental sensitivity and expected direct CP violation in the charm sector.
This paper presents a feasibility study demonstrating that the proposed Super Tau-Charm Facility (STCF) can effectively probe quantum entanglement and Bell-inequality violations in pairs via the decay channel, achieving a reconstructed concurrence of through full Monte Carlo simulations at GeV.
This paper introduces HepScript, a dual-use Domain-Specific Language for High-Energy Physics that serves as a formal interface to abstract complex analysis logic, enabling human experts to write concise code while allowing AI agents to reliably generate executable specifications from literature, thereby significantly reducing manual effort and solving previously intractable automation challenges.
This paper investigates heavy meson pair correlations in forward proton-nucleus collisions by incorporating unified Sudakov resummation within the Color Glass Condensate framework, demonstrating good agreement with LHCb data and predicting a robust mass hierarchy in nuclear suppression that highlights the sensitivity of heavy quarks to gluon saturation effects.
