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 Letter of Intent outlines a proposal to develop a future experiment at the High-Intensity Muon Beam facility at PSI, aiming to improve current sensitivity by over an order of magnitude within the next decade to maintain leadership in searching for charged lepton flavor violation.
This paper investigates how a polarized electron beam at the proposed "Chiral Belle" upgrade of Belle II can distinguish the spin and Lorentz structure of invisibly decaying dark bosons by analyzing the polarization dependence of the mono-photon production channel ().
This paper proposes using asymmetric beam energies at muon colliders to boost forward muons into detector acceptance, thereby overcoming shielding limitations and improving the reconstruction of vector boson fusion processes like VBF Higgs production.
This paper surveys approximately 70 rare and exclusive few-body Standard Model Higgs boson decays with branching fractions below , providing theoretical predictions, current experimental limits, and HL-LHC projections—including 20 newly computed channels—to guide future research in constraining couplings, probing flavor-changing processes, and estimating backgrounds for exotic physics.
This paper demonstrates that a modified Double Logarithmic Approximation incorporating energy conservation accurately describes the inclusive charged-particle multiplicity distributions of quark- and gluon-initiated jets in 13 TeV $pp$ collisions, showing consistency with both ATLAS experimental data and PYTHIA simulations.
This paper utilizes the observed 11-year jet precession period of M87* to constrain the parameters of a rotating black hole in Bumblebee gravity, demonstrating how Lorentz-symmetry breaking affects spherical orbits and innermost stable spherical orbits, and suggesting that a warp radius exceeding 16 may indicate the presence of a non-vacuum Bumblebee vector field when combined with EHT shadow constraints.
This paper presents a first-principle model explaining low-energy radon-induced backgrounds from electrode grids in dual-phase xenon TPCs, which aligns with data from the LZ and LUX experiments and offers strategies for mitigating these backgrounds in future dark matter searches.
FeynGame 3.0 is a major software update that introduces QGRAF integration for visualizing Feynman graphs and implements various new features to facilitate the creation of publication-quality diagrams.
This paper presents the first evidence of medium response to hard probes in heavy ion collisions by observing significant modifications in the distributions of low transverse momentum hadrons recoiling against Z bosons in lead-lead collisions, consistent with theoretical predictions of a hydrodynamic wake generated by energy depletion in the quark-gluon plasma.
This paper presents the full Lorentz decomposition of the tensor form factors for the baryon induced by both isovector and isoscalar currents, revealing distinct contributions from up and down quark components that reflect the baryon's internal structure and spin distribution.
