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.
Using QCD two-point sum rules, this study quantitatively analyzes how the mass and decay constant of the meson in a hot and dense medium initially increase with temperature or baryon chemical potential before reaching a maximum and eventually vanishing at critical values that shift to lower thresholds as the opposing parameter increases.
This paper presents a review of projected sensitivities for precision Higgs boson measurements at a 10 TeV muon collider, demonstrating that with 10 ab⁻¹ of integrated luminosity, the facility could achieve sub-percent precision on key production cross sections, a 19 MeV precision on the Higgs mass, and a 5% determination of the trilinear Higgs self-coupling through detailed simulations of the MUSIC detector.
This paper presents the design and performance validation of a dedicated data acquisition system for the SUBMET experiment at J-PARC, which utilizes cascaded DRS4 chips to achieve high-speed, low-noise single-photoelectron detection and precise timing synchronization across multiple channels to search for millicharged particles.
This paper applies transfer learning to fine-tune deep neural networks pretrained on carbon-12 data, successfully constructing robust, data-driven models for inclusive electron-nucleus cross sections across various nuclei that outperform existing phenomenological models while systematically analyzing the impact of fine-tuning depth, data availability, and kinematic coverage.
This paper summarizes recent results from the NA61/SHINE experiment at CERN, covering strong interaction studies in various collision systems including rapidity spectra, yield dependencies, transverse polarization, and evidence of isospin symmetry violation in kaon production.
The NOvA collaboration reports the first dual-baseline search for active-to-sterile neutrino oscillations using both neutrino- and antineutrino-enriched samples, finding no evidence for sterile neutrinos and excluding parameter regions previously allowed by other experiments, including most of IceCube's allowed region.
The paper introduces G4VR, a virtual reality extension for the Geant4 toolkit that utilizes a new visualization driver (G4XR) to enable immersive, interactive 3D exploration of particle interactions, tracks, and event chronologies through headsets and hand controllers.
This paper proposes that a high-energy nuclear recoil candidate observed by the LUX-ZEPLIN experiment can be explained by singlet-doublet Majorana dark matter undergoing spin-dependent scattering via a boson, a scenario that simultaneously satisfies thermal relic constraints, evades low-energy background limits through a Higgs blind spot, and remains testable via solar neutrino searches.
Using the full Run 2 dataset from the ATLAS experiment at TeV, this study searches for low-mass dijet resonances produced in association with a photon or a jet, finding no evidence of new physics and setting new upper limits on production cross-sections for masses between 200 and 650 GeV.
This paper presents the design, calibration, and performance validation of the upgraded prototype Schwarzschild-Couder Telescope camera module, which features 11,328 silicon photomultiplier pixels and improved electronics to achieve low noise and excellent charge resolution for the Cherenkov Telescope Array Observatory.
