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 study reports the first laser-shock experiments on high entropy alloy microfilms probed by an X-ray free electron laser, revealing a transient 5.1% lattice compression under approximately 55 GPa of shock pressure and demonstrating the feasibility of using this technique to determine the equation of state for these emerging materials.
This paper constructs a global function designed for the simultaneous fitting of correlated energy-dependent cross sections by incorporating correlations between different processes and energy points, as well as uncertainties from integrated luminosity and center-of-mass energy measurements.
This paper employs a quark combination model within a hadronic coalescence framework to systematically analyze the production of light nuclei and hypernuclei in Au-Au collisions across the RHIC Beam Energy Scan, successfully explaining existing experimental data for species like deuterons and hypertritons while predicting yields for various -hypernuclei and exploring their production correlations as a function of collision energy.
This paper reports the commissioning of a new Penning-Malmberg trap at CERN's GBAR experiment that achieves a record accumulation of over antiprotons in under 35 minutes and delivers antiprotons per shot with reduced emittance, significantly enhancing the production rate of antihydrogen beams for gravitational studies.
This paper introduces the hyperbolic form factor as a bilateral Laplace transform of density distributions to model Yukawa interactions mediated by massive particles, applying it to Earth's density profile to derive significantly relaxed coupling limits for new spin-0 and spin-1 mediators with masses around eV/.
This paper reviews the motivations, design strategies, and multimessenger significance of Cherenkov neutrino telescopes, emphasizing their unique capability to probe cosmic ray origins and the universe's most energetic phenomena.
This study characterizes the long-range muon background at the SND@LHC experiment during LHC Run-3 by validating Monte Carlo simulations against measurements, identifying a persistent flux increase due to ATLAS horizontal crossing and diffractive losses, and confirming that upcoming detector upgrades will maintain efficiency despite projected rate rises in the High-Luminosity LHC era.
Using 13 TeV proton-proton collision data collected by the CMS experiment, this study searches for low-mass vector and scalar resonances decaying into quark-antiquark pairs and, finding no evidence of such signals, sets the most stringent limits to date on their couplings in the 50–250 GeV mass range.
Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at as measured by ATLAS.
Using 138 fb of proton-proton collision data at 13 TeV collected by the CMS experiment, this study presents the first dedicated search for highly Lorentz-boosted Higgs bosons decaying to WW pairs, finding no evidence of a signal above background with a measured signal strength of = $-$0.19.
