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.
The XENONnT experiment has reported the first measurement of nuclear recoils from solar B neutrinos using coherent elastic neutrino-nucleus scattering, providing a solar neutrino flux and cross section consistent with Standard Model predictions.
This paper proposes a unified framework for analyzing the Berry phase in axion-photon and axion-fermion interactions, suggesting that measuring this phase can serve as a novel method for detecting axions and probing the Standard Model's global structure and generalized symmetries.
This paper presents a unified quantum mechanical framework for detecting ultralight scalar dark matter via matter effects, revealing novel non-perturbative phenomena like descreening that alleviate decoherence suppression and refining experimental constraints on background-induced forces beyond the spherical approximation.
This paper investigates the fabrication and characterization of AlMn alloy superconducting films, demonstrating that their critical temperature can be tuned to the 10–20 mK range through annealing and studying its sensitivity to magnetic fields, which is essential for developing transition edge sensors (TES) for next-generation neutrinoless double-beta decay experiments.
This study details the fabrication and characterization of X-ray transition edge sensors (TESs) using unique annular AlMn alloy films, achieving an energy resolution of 11.0 eV at 5.9 keV.
This paper reviews recent progress in calculating the hadronic contributions to the muon's anomalous magnetic moment—specifically hadronic vacuum polarization and hadronic light-by-light scattering—using Resonance Chiral Theory, finding results consistent with the White Paper 2 values.
This study analyzes a high-quality sample of 36 wide binary stars with precise 3D velocities to demonstrate a statistically significant () gravitational anomaly at low accelerations, finding a gravity boost factor of that contradicts standard Newtonian gravity and supports nonstandard paradigms like MOND.
This study investigates how non-extensive statistics and hadronic composition influence the drag, diffusion, and relaxation properties of hadrons in a thermal bath, revealing that increasing the non-extensivity parameter and mass cutoffs enhances momentum transport while decreasing spatial diffusion.
The paper proposes the Poisson Log-Normal (PoLoN) process, a non-parametric framework that utilizes Gaussian processes to model Poisson log-rates, enabling effective prediction, signal detection, and parameter extraction for discrete count data.
The paper introduces FPPDF, a new open-source tool that implements the MSHT collaboration's polynomial parameterization and Hessian error approach using NNPDF's theoretical and experimental libraries, ultimately demonstrating that the impact of moving to aNLO perturbative orders is largely independent of the chosen PDF parameterization methodology.
