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 reports the first measurement of the cosmic muon flux at the Stawell Underground Physics Laboratory using eight plastic scintillator panels, yielding a value of (6.33 ± 0.04_stat ± 0.35_sys) × 10⁻⁸ s⁻¹ cm⁻² that aligns well with simulations and features significantly reduced uncertainty compared to modeling.
This paper proposes that the Dark Technicolour paradigm, utilizing the Extended Most Attractive Channel hypothesis across three confining gauge sectors, revitalizes conventional Technicolour dynamics to generate Standard Model fermion masses and resolve the Flavor Problem through a hierarchical structure of multifermion condensates.
Using 137 fb⁻¹ of 13 TeV proton-proton collision data from the ATLAS detector, this study searches for long-lived particles via displaced vertices and missing transverse momentum, finding no significant excess over Standard Model backgrounds and setting 95% confidence-level limits on four specific beyond-the-Standard Model scenarios.
This paper introduces PoLAr-MAE, a self-supervised masked point modeling framework for Liquid Argon Time Projection Chamber (LArTPC) data that learns physically meaningful trajectory representations from unlabeled events, achieving state-of-the-art segmentation performance with minimal labeled data and demonstrating the potential for a universal foundation model in particle physics.
This paper investigates the sensitivity of a 2 TeV same-sign muon collider (μTRISTAN) to eight distinct dimension-seven SMEFT operators via processes, demonstrating its potential to probe lepton number violation beyond existing LHC constraints and future FCC projections.
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 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.
