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 presents two ATLAS searches for massive, long-lived particles decaying into displaced vertices using Run 2 missing transverse energy and Run 3 muon triggers, introducing novel reconstruction and trigger techniques to set limits on various Beyond the Standard Model scenarios including Higgs Portal, SUSY, and axino models.
This paper presents LHCb measurements of the branching fraction for the decay and form factor parameters for the decay, which serve as powerful probes for testing the Standard Model and searching for New Physics.
The ATLAS Collaboration reports a significant excess of top-antitop events near their production threshold in 13 TeV proton-proton collisions, a finding consistent with the long-hypothesized formation of top-antitop quasi-bound states.
This paper presents a theorist's perspective on utilizing various non-leptonic and rare B meson decays as probes for CP violation at the Future Circular Collider (FCC) in the post-HL-LHC and Belle II era.
This paper presents an updated analysis of the long-standing puzzle by incorporating recent Belle II measurements of CP asymmetries in the decay, offering new insights into potential sources of CP violation beyond the Standard Model.
This paper evaluates the physics potential of a 10 TeV muon collider using the MUSIC detector concept and 10 ab of integrated luminosity, demonstrating its exceptional capability to precisely measure key Higgs processes and determine the trilinear self-coupling with a level of precision unattainable by other proposed future colliders.
Using 138 fb of proton-proton collision data at 13 TeV collected by the CMS experiment, this study searches for single-produced vector-like quarks decaying into a W boson and a b quark in single-lepton final states, finding no significant excess over the Standard Model and setting the most stringent limits to date on their production cross section and coupling strength.
This paper presents results from the Belle and Belle II experiments on rare electroweak penguin decays involving missing energy, specifically analyzing , , and transitions using a 1.3 ab dataset collected at the resonance.
This paper argues that the observed sequential suppression of and states in high-multiplicity $pp$ collisions cannot be explained by standard hadronic or string-based models, but instead provides compelling evidence for the formation of an early, globally correlated partonic medium.
This paper outlines LHCb's competitive forward physics program, detailing complementary heavy-flavour jet measurements, electroweak studies involving top and W bosons, and searches for exotic new physics states such as axion-like particles, heavy-neutral leptons, and rare B-meson decays.
