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 transverse momentum spectra of pions, kaons, and protons in heavy-ion collisions across various energies and centralities exhibit universal scaling when normalized by global physical quantities, a phenomenon explained via the Cooper-Frye formula and shown to be equivalent to the Hwa-Yang scaling.
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 establishes a quantitative framework linking local spin polarization and quantum entanglement in two-qubit systems by deriving an upper bound on concurrence that decreases with increasing polarization, a relationship demonstrated to be saturated by pure states in high-energy processes like .
This paper proposes that the decay exhibits large CP violation with asymmetries up to 50% and offers a novel strategy to extract the CKM angle by combining angular distribution parameters and decay rates, positioning this channel as a prime target for future LHCb investigations.
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.
