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 the first comprehensive theoretical study of the rare Dalitz decay , predicting its branching fraction and dilepton spectrum to establish it as a new probe for hadronic structure and a sensitive channel for searching for light dark photons at the BESIII experiment.
This paper reviews recent multiboson and vector boson scattering measurements from the ATLAS and CMS collaborations at the LHC, including new results at 13.6 TeV, which collectively provide a comprehensive test of the Standard Model's electroweak sector and stringent constraints on anomalous gauge couplings.
This paper analyzes 7 TeV LHCb Collaboration data on two- and three-pion Bose-Einstein correlations by combining the Glauber-Lachs formula with a two-component pion production model, utilizing specific pion exchange functions extended into four-dimensional Euclidean configuration space.
Using LHCb data at TeV, this study presents the first observation of the decay, measuring its branching ratio relative to the charged mode and finding evidence for the isospin partners and in the system.
This paper presents recent LHCb results on rare and very rare decays of third-generation particles, including first searches and the most stringent limits to date for processes such as , , , and , which serve as sensitive probes for physics beyond the Standard Model.
This paper outlines the ATLAS experiment's ongoing strategies to evaluate and mitigate the environmental impact of its massive, globally distributed computing infrastructure in preparation for the significantly increased resource demands of the High-Luminosity LHC era.
This paper presents a 63-day cosmic-ray scattering experiment using Resistive Plate Chambers to simultaneously measure secondary cosmic-ray composition with high precision and establish stringent constraints on muon-philic dark matter scattering cross-sections.
This paper proposes that a hypothetical color-octet, electroweak-singlet scalar particle () could explain a excess in CMS 4-jet data at a dijet mass of approximately 0.95 TeV, with a complex scalar variant providing a better fit to the observed signal shape and rate than a real scalar.
This paper introduces and evaluates a new W-based neutrino energy estimator for liquid-argon time-projection chambers, demonstrating that while it offers superior robustness against modeling uncertainties and minimal bias in the transition region between scattering regimes, its slightly worse energy resolution under ideal conditions suggests a complementary role alongside more exclusive methods for future oscillation analyses.
This paper presents a precision Standard Model analysis and new physics projections for the radiative decay at the LHC, demonstrating its potential to measure the branching ratio with sub-percentage accuracy and to probe axion-like particles and anomalous gauge bosons with enhanced sensitivity down to couplings of .
