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 paper experimentally demonstrates the detection of momentum transfers from individual gas collisions with an optically levitated nanoparticle, validating theoretical models and establishing a proof-of-principle for primary pressure sensors and precision measurements of fundamental particle interactions.
This paper presents the design and simulation results of a positron transport system for the Muonium-to-Antimuonium Conversion Experiment (MACE), demonstrating high geometric acceptance, precise position resolution, and a time-of-flight capability that enables a rejection factor for internal conversion backgrounds to facilitate the search for charged lepton flavor violation.
This paper reviews recent precision measurements of Standard Model W and Z boson production (including Z+jet and boosted W decays) by the ATLAS and CMS collaborations using Run 2 data, highlighting their role in rigorously testing perturbative QCD, electroweak theory, and parton distribution functions.
This paper presents the first measurement of open-charm baryon-to-meson ratios, specifically the baseline, in + collisions at RHIC energies using the high-statistics, unbiased dataset collected by the sPHENIX experiment to investigate heavy-flavor hadronization mechanisms.
This paper presents a theoretical study of charged current -induced deep inelastic scattering on at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.
This paper investigates rare dileptonic decays of , , and baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.
This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.
This paper proposes a novel high-luminosity experimental approach using tagged hyperons produced in proton-proton collisions within a nested-target setup to precisely measure hyperon-nucleon interactions, thereby addressing the uncertainties in the equation of state that underlie the hyperon puzzle in neutron stars.
This paper presents a systematic study of semi-leptonic Higgs decays to electroweak gauge bosons at NLO QCD and electroweak accuracy, demonstrating that while finite fermion masses and higher-order corrections significantly modify angular observables, the process retains an effective two-qutrit description suitable for quantum tomography and entanglement analysis.
The FASER experiment presents its latest physics results from LHC Run 3, featuring world-leading dark photon exclusion limits, the first observation of electron neutrinos, and pioneering measurements of neutrino cross sections and charm hadron production using both emulsion and electronic detectors.
