hep-ex papers | Gist.Science

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.

Vector boson scattering and anomalous quartic couplings in final states with $\ell\nu$ qq or $\ell\ell$ qq plus jets using proton-proton collisions at $\sqrt{s}$ = 13 TeV

Using 138 fb $^{-1}$ of proton-proton collision data at 13 TeV collected by the CMS detector, this study presents a measurement of electroweak ZV (V=W, Z) boson pair production with two jets, achieving an observed significance of 1.3 standard deviations and setting world-leading constraints on anomalous quartic gauge couplings through a combination with previous WV channel results.

Evidence of Higgs boson inclusive production at high transverse momentum decaying to a pair of $b$ -quarks with the ATLAS detector

Using 301 fb $^{-1}$ of proton-proton collision data at 13 and 13.6 TeV collected by the ATLAS detector, this study reports the first evidence of Higgs boson inclusive production at high transverse momentum ( $p_{\text{T}} > 450$ GeV) decaying to a $b\bar{b}$ pair, achieving a 3.8 $\sigma$ observed significance through advanced jet identification and regression techniques.

Measurement of the transverse-momentum fraction of strange hadrons from jet-like correlation structures in pp collisions at $\sqrt{s} = 13$ TeV

The ALICE Collaboration reports the first measurements of the average transverse-momentum fraction for strange hadrons in 13 TeV pp collisions, revealing distinct production trends for mesons and baryons that current Monte Carlo models fail to describe.

Understanding Bell locality tests at colliders

This paper demonstrates that while local hidden variable theories were previously considered untestable in collider experiments, they can now be disproved for decaying particles like $\mu^+ \mu^-$ and $\tau^+ \tau^-$ pairs by applying Bell-like inequalities under a small set of mild assumptions.

Global Analyses of Generalized Parton Distributions with Diverse PDF Inputs

This paper presents six global analyses of generalized parton distributions (GPDs) at zero skewness using various modern PDF sets and factorization scales, demonstrating that NNPDF40 at NLO provides the best fit to elastic electron scattering data while revealing moderate sensitivity to PDF inputs and perturbative orders.
