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 demonstrates that using a linearized mixing approximation to study heavy neutrino contributions in yields physically incorrect results due to unitarity violations, whereas an exact unitary mixing scheme provides reliable, experimentally testable signatures for future colliders.
This paper outlines the current understanding of how International Linear Collider detector concepts can be adapted for future Higgs Factory facilities with different properties, such as the FCC-ee.
This paper demonstrates that the recently observed need for a right-handed vector boson admixture in neutron decay successfully explains CP-violation effects in neutral meson oscillations (, , , and ) within an extended left-right weak interaction model, suggesting that the nature of CP violation is fundamentally linked to the presence of right-handed currents.
This paper presents a comprehensive Bayesian MCMC analysis of the meson spectrum using standard and logarithmically modified Cornell potentials to rigorously quantify uncertainties, probe the sensitivity of excited states to confinement forms, and provide updated theoretical predictions for future experimental benchmarks.
This paper derives updated supernova constraints on muon-philic scalars and pseudoscalars by incorporating two-photon couplings from muon triangle loops, revealing that while globular-cluster limits dominate for light masses, supernova 1987A gamma-ray observations and energy-loss arguments impose stringent bounds on heavier masses that challenge the viability of these bosons explaining the muon magnetic-moment anomaly.
This paper proposes an upgraded haloscope design that significantly enhances axion detection sensitivity by 3 to 4 orders of magnitude through the application of a transverse radio-frequency modulated magnetic field to generate first-order axion-photon energy response signals.
This paper proposes a novel framework where a spontaneously broken global symmetry generates a residual symmetry that stabilizes dark matter while suppressing proton decay to the one-loop level, thereby linking the proton lifetime to dark matter mass and predicting distinctive TeV-scale leptoquark signatures accessible to current and future experiments.
This paper proposes a novel method to extract non-singlet fragmentation functions for pions and kaons at next-to-next-to-leading order in QCD by analyzing charge asymmetries in electron-positron annihilation and semi-inclusive deep-inelastic scattering, revealing key properties like a scaling index of 0.7 and a strangeness suppression factor of 0.5 that serve as benchmarks for QCD models and future electron-ion collider inputs.
This paper presents and validates a novel diode-based symmetric charge division multiplexing scheme that significantly reduces the readout channel count for plastic scintillating fiber detectors while maintaining high detection efficiency (>95%) and spatial resolution (~0.65 mm), offering a scalable and cost-effective solution for large-area muon tomography systems.
This paper proposes using symmetry arguments to construct form-factor-independent angular observables in hadronic decays, offering a clean experimental test for physics beyond the Standard Model or long-distance electromagnetic corrections.
