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 systematically investigates the magnetic moments and M1 radiative decays of predicted molecular pentaquarks using the constituent quark model across multiple analysis scenarios, demonstrating that these electromagnetic properties serve as sensitive probes for determining their inner structures and quantum numbers while identifying promising channels for future experimental detection.
This Letter presents an improved, model-independent calculation of radiative corrections to decays that incorporates structure-dependent effects beyond point-like pions and threshold enhancements, thereby refining the precision of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment derived from tau decay data.
The paper introduces NuFast-Earth, a fast, flexible, and accurate C++ algorithm designed to efficiently compute neutrino oscillation probabilities for atmospheric, nighttime solar, and supernova neutrinos traversing the Earth's varying density profiles, thereby addressing the growing computational demands of next-generation neutrino experiments.
This paper demonstrates that a minimally extended Georgi-Machacek model can naturally explain the observed LHC and LEP excesses at 95 GeV and 152 GeV through specific features like light scalar masses and enhanced diphoton decays, while predicting additional light scalars and offering promising prospects for future discovery at the HL-LHC and colliders.
This paper presents the design, construction, and successful operation of a dual-phase xenon time projection chamber prototype for the RELICS experiment, demonstrating its ability to achieve the required sub-keV energy threshold and validating the core technologies and methodologies essential for the full-scale coherent elastic neutrino-nucleus scattering detector.
This paper improves theoretical predictions for rare -boson decays into heavy vector quarkonium and lepton pairs by including all relevant Standard Model tree-level diagrams, revealing that while fragmentation dominates charmonium channels, additional diagrams increase bottomonium branching fractions by 4–9%, and confirming that forward-backward asymmetries vanish in the Standard Model to provide a baseline for future experimental tests.
This paper presents a novel unsupervised deep learning method that utilizes a simplified physical model of optical photon transport to automatically extract photomultiplier tube calibration constants from radioactive background events in the large-scale SNO+ liquid scintillation detector.
This paper presents the first complete next-to-leading-order calculation of BFKL impact factors for the hadroproduction of specific NRQCD quarkonium states by combining virtual corrections with real-emission contributions, demonstrating the cancellation of soft divergences and the compatibility of surviving collinear singularities with factorization to enable future next-to-leading-logarithmic precision studies.
This paper validates the chemical and mechanical robustness of the COSINE-100U NaI(Tl) encapsulation for low-temperature operation in liquid scintillator by demonstrating stable performance over approximately 150 days at -33°C following initial compatibility checks.
Using an effective Lagrangian approach calibrated to existing data, this study successfully reproduces the production cross sections of high-spin and mesons in reactions and predicts measurable, forward-peaked production rates for their partners, suggesting their feasibility for observation in future meson-beam experiments.
