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 investigates resonant triple Higgs production within the Next-to-minimal Two Higgs Doublet Model (N2HDM), demonstrating that interference effects and additional decay channels significantly alter kinematic distributions and necessitate fully differential studies over simplified approximations to accurately probe extended Higgs sectors at the LHC.
Using 164 fb of 13.6 TeV proton-proton collision data collected by the ATLAS detector, this study measures the cross section, sets the most stringent single-measurement upper limit on production, and provides the most direct constraints to date on the CP structure of the Higgs-top Yukawa interaction by excluding a purely CP-odd coupling at 5.8 standard deviations.
This paper proposes a ferromagnet lattice magnetometer that coherently combines multiple levitated ferromagnets to significantly enhance sensitivity for detecting ultralight dark matter by suppressing dipole-dipole interactions and leveraging collective readout, thereby surpassing existing single-ferromagnet constraints across various coupling models.
This paper presents the next-to-next-to-leading logarithmic (NNLL) collinear resummation of projected -point energy correlators up to , incorporating newly computed two-loop jet functions and leading non-perturbative corrections, thereby establishing quantitative control over these observables for future precision extractions.
This paper constructs an explicit model where a Dirac fermion dark matter candidate is boosted via semi-annihilation into anti-dark matter and neutrinos, simultaneously generating radiative neutrino masses at the two-loop level, and demonstrates that a mediator mass of MeV enhances the elastic scattering cross section to levels detectable by future experiments like DUNE and DARWIN.
This paper elucidates how the Chiral Quark Soliton Model (CQSM), by uniquely incorporating non-local quark-quark correlations arising from spontaneous chiral symmetry breaking, successfully predicts various nucleon parton distribution functions, particularly the flavor asymmetry of sea-quark distributions, outperforming traditional effective meson theories like the Skyrme model.
This paper presents the first search for electroweak-scale dijet resonances in the 100–250 GeV mass range using pile-up collisions recorded by the ATLAS detector at TeV, a novel strategy that bypasses high jet trigger thresholds to probe low-mass hadronic resonances without observing any significant excess over Standard Model expectations.
This paper presents preliminary studies and analysis ideas for tagging scattered charged fragments using the ATLAS Forward Proton detectors during the 2025 LHC oxygen and neon collision campaign.
Using proton-proton collision data at = 13.6 TeV collected by the CMS detector, this paper presents the most precise measurement to date of the mixing angle in the Higgs boson coupling to tau leptons, yielding a combined result of (7 16) that is consistent with the Standard Model prediction of a purely scalar interaction.
The paper proposes a Rydberg-atom-based single-photon detector for dark matter haloscope experiments in the 10–50 GHz frequency range, which overcomes quantum measurement noise limitations of standard linear amplifiers to achieve scan rate enhancements up to for searching QCD axions with masses above 40 eV.
