2503 papers

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.

Prospects for precision Higgs boson measurements at a 10 TeV muon collider

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.

Readout electronics for SUBMET

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.

Inclusive electron-nucleus cross section models from domain adaptation

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.

NOvA Dual-Baseline Search for Active-to-Sterile Neutrino Oscillations using Neutrino- and Antineutrino-Enriched Samples

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.

A Vector-Like Lepton Interpretation of the High-Energy Nuclear Recoil Candidate in LUX-ZEPLIN

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 ZZ 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.

Search for low-mass resonances decaying into two jets and produced in association with a photon or a jet at s=13\sqrt{s}=13 TeV with the ATLAS detector

Using the full Run 2 dataset from the ATLAS experiment at s=13\sqrt{s}=13 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.

Spin-dependent azimuthal asymmetry of coherent J/ψ\psi photoproduction in hadronic PbPb collisions at sNN\sqrt{s_\mathrm{NN}} = 5.36 TeV

Using CMS data from 5.36 TeV PbPb collisions, this study reports the first observation of a significant negative spin-dependent azimuthal asymmetry in coherently photoproduced J/ψ\psi mesons, confirming a theoretical model where the meson inherits the incident photon's linear polarization and suggesting a novel method for reaction plane determination.
