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 the minimal type II seesaw mechanism with two-zero neutrino mass textures, demonstrating how specific patterns of charged lepton flavor violation—particularly in tau decays—can be distinguished from other new physics scenarios and used to probe ultra-high flavor symmetry scales and doubly charged scalars at current and future experiments.
This paper proposes a machine-learning-based strategy that classifies neutrino interaction types prior to energy reconstruction to exploit intrinsic kinematic differences, thereby reducing modeling uncertainties and improving the accuracy and sensitivity of next-generation long-baseline oscillation experiments like DUNE by 10–20%.
This paper presents a detailed computer simulation method to investigate the non-monotonic evolution of K-shell ionization and characteristic x-ray radiation angular distributions from high-energy electrons and positrons traversing oriented silicon crystals across a wide energy range (1–1000 GeV), with a specific focus on the underlying physical mechanisms such as dechanneling.
This paper presents the latest results from the ATLAS and CMS experiments on precision measurements of top-quark pair spin correlations and quantum entanglement, leveraging extensive proton-proton collision datasets at up to 13.6 TeV to test theoretical predictions through the unique decay properties of top quarks.
Using the perturbative QCD approach, this paper analyzes resonance contributions from and mesons and their excited states to the three-body decays , revealing that virtual contributions from the tails of and are comparable to those from higher resonances and thus constitute a significant component of these decays.
This paper presents a comprehensive framework for modeling complex systems of oscillating and decaying neutrinos using open quantum system methods, specifically demonstrating that the Lindblad master equation, Liouvillian superoperator, and Kraus operators offer a fully general and numerically superior approach compared to traditional differential equation solutions.
This paper introduces the Particle transformer (PaRT), a novel deep neural network based on self-attention that achieves high-efficiency tagging of Lorentz-boosted Higgs bosons decaying to W boson pairs in CMS data while maintaining decorrelation from jet mass, thereby enhancing the sensitivity of Standard Model measurements and beyond-the-Standard-Model searches.
This proceeding summarizes recent studies on semileptonic and leptonic decays using combined Belle and Belle II datasets to test lepton flavour universality and improve the precision of inclusive and determinations.
The NA61/SHINE Collaboration presents results from a comprehensive two-dimensional scan of collision energy and system size to investigate the onset of deconfinement and baryon transport mechanisms in strongly interacting matter, highlighting key findings such as the ratio and comparisons with previous NA49 data.
This paper presents a brief biography of William A. Bardeen (1941–2025), an American theoretical physicist at Fermilab renowned for his foundational contributions to the chiral anomaly, quantum chromodynamics, dynamical electroweak symmetry breaking, and heavy-light quark bound states.
