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 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.
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.
This paper proposes that a compressed mass spectrum scenario in the type-II seesaw model, which has likely evaded previous LHC searches, can be effectively probed using multivariate analysis of same-sign dilepton events with low invariant mass on existing Run 2 and future HL-LHC data.
This paper proposes that an triplet scalar with hypercharge and a small mixing angle with the Standard Model Higgs can explain the 95 GeV diphoton excess through Drell-Yan production, predicting distinct kinematic signatures, an associated charged Higgs state near 95 GeV, and a positive shift in the W boson mass.
This paper analyzes the theoretical constraints, electroweak precision predictions, and LHC phenomenology of the Standard Model extended by a real Higgs triplet, finding that while current searches exclude charged Higgs masses below 110 GeV, a specific signal region excess at 152 GeV suggests a statistically significant preference for a non-zero di-photon branching ratio of the neutral triplet Higgs.
The TUCAN collaboration reports significant progress in commissioning its high-intensity accelerator-driven ultracold neutron source and developing the associated spectrometer, achieving the first UCN production in 2024 and setting the stage for a neutron EDM experiment with a sensitivity goal of and two orders of magnitude improved statistics.
