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 investigates isospin-breaking effects in double-charm molecular pentaquarks using a one-boson-exchange potential framework, revealing that these effects induce significant 10–30% corrections to binding energies—particularly in loosely bound states—and are therefore essential for achieving the theoretical precision required to match advancing experimental programs.
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.
Using a combined dataset of 1.4 ab⁻¹ from the Belle and Belle II experiments, this paper presents new measurements of branching fractions for and baryons, including several first observations, and reports an initial search for CP violation in singly Cabibbo-suppressed three-body decays to test U-spin symmetry.
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.
This paper reports the first exclusion limits on axion dark matter derived from a cryogenic, magnetized DALI prototype, which analyzed 36 hours of data to set a new sensitivity bound of in the 6.883–6.920 GHz band without detecting a signal.
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.
This mini-review highlights the BESIII experiment's critical role in probing non-perturbative QCD dynamics and searching for new physics by presenting the latest stringent upper limits on rare charmonium weak decays, including flavor-changing neutral currents, derived from its unprecedented dataset of over and events.
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.
This paper conducts a comprehensive study of the Type-II see-saw mechanism with a non-degenerate triplet Higgs spectrum, deriving updated 95% CL lower limits on the doubly charged scalar mass that exceed current LHC constraints by 50–230 GeV while identifying unconstrained parameter regions and proposing improved search strategies for the high-luminosity phase.
