2585 papers

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.

Predicting Three Generations of Fermions: Discovery Prospects of the Bilepton Model

This paper investigates the discovery potential of doubly-charged bileptons at the High-Luminosity LHC through direct pair production and heavy-quark-mediated channels, demonstrating that the latter offers significantly enhanced sensitivity capable of achieving a 5σ5\sigma discovery for heavy quark masses up to 2.5 TeV and bilepton masses up to 2 TeV due to a distinctive, background-free four-lepton signature.

First measurements of vector boson scattering in W±^\pmW±^{\pm} and WZ production in all-leptonic final states at s\sqrt{s} = 13.6 TeV

Using 171 fb−1^{-1} of proton-proton collision data at s\sqrt{s} = 13.6 TeV collected by the CMS detector, this paper reports the first measurements of W±^\pmW±^\pm and WZ vector boson scattering cross sections in all-leptonic final states, achieving a significance greater than five standard deviations for both processes.

Numerical Study of MRW-Type Unintegrated Double Parton Distribution Functions from Non-Factorized DPDFs

This paper presents a numerical study of MRW-type unintegrated double parton distribution functions constructed from non-factorized GS09 collinear DPDFs, comparing the performance and characteristics of double modified KMRW, double virtuality ordered MRW, and a normalization-matched variant to analyze their transverse momentum dependence, normalization properties, and sensitivity to longitudinal correlations.

Inclusive charm and bottom quark pair production cross sections at hadron colliders at next-to-next-to-leading-order accuracy

This paper presents a comprehensive study of inclusive charm and bottom quark pair production cross sections across a wide range of collision energies using next-to-next-to-leading-order (NNLO) calculations with the new MaunaKea code, demonstrating that these advanced predictions significantly enhance accuracy and reduce theoretical uncertainties compared to previous NLO results, thereby achieving agreement with experimental data and offering valuable constraints on gluon density and the bottom-quark mass.

Detecting dark matter using optically trapped Rydberg atom tweezer arrays

This paper proposes a novel scheme for detecting wave-like dark matter, specifically dark photons, by utilizing large ensembles of Rydberg atoms trapped in optical tweezer arrays to observe DM-induced excitations between energy levels, with the ability to scan different dark matter masses via external magnetic field tuning.
