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 demonstrates that if a symmetry responsible for generating light Dirac neutrino masses is spontaneously broken, it can radiatively induce the explicit breaking necessary to destabilize domain wall networks, thereby creating a predictable link between the Dirac neutrino mass scale and a detectable stochastic gravitational wave signal.
This paper discusses the increasing integration of machine learning techniques within the CMS experiment to enhance the reconstruction and identification of physics objects in both online and offline settings, while highlighting its critical role in preparing for the high-luminosity LHC era.
This paper evaluates the commissioning and performance of b-jet triggers within the CMS High-Level Trigger system using Run-3 data to optimize real-time heavy-flavor jet selection.
This paper presents the latest direct and indirect measurements from the CMS experiment regarding the challenging task of constraining light Higgs Yukawa couplings, such as the Higgs-charm coupling, and discusses future prospects for improvement.
This paper presents EPOS4 model predictions for pp, O-O, and Pb-Pb collisions at LHC Run 3 energies, demonstrating that the dynamical core-corona approach and hadronic-phase effects (via UrQMD) are essential for describing the non-universal scaling of transverse momentum, identified-hadron spectra, and nuclear modification factors across different system sizes.
This paper presents an updated analysis of the Borexino Phase-III data set to provide improved constraints on flavor-diagonal non-standard neutrino interactions and offers a first-of-its-kind comprehensive exploration of all possible off-diagonal NSI terms.
This paper demonstrates that even in high-statistics counting experiments, finite Monte Carlo sample sizes used to model systematic uncertainties cause the standard asymptotic approximations for profile-likelihood ratio confidence intervals to fail, resulting in systematic under-coverage.
This paper reviews collider phenomenology, highlighting how current and future colliders serve as ideal testing grounds for (sub)TeV-scale neutrino mass models by directly probing associated messenger particles and leveraging recent LHC observations of TeV-scale neutrinos to test the limits of the Standard Model.
Using the ATLAS detector, this paper presents a search for R-parity-conserving supersymmetry in proton-proton collisions at 13 and 13.6 TeV involving tau-leptons, jets, and missing transverse momentum, which excludes gluino masses below 2.25 TeV and squark masses up to 1.7 TeV based on 140 fb⁻¹ and 51.8 fb⁻¹ of data.
The NA62 experiment at CERN reports a search for heavy neutral leptons in decays using 2017–2024 data, establishing upper limits on the mixing element at the level of for particle masses between 95 and 126 MeV/.
