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.

Dependence of two-particle azimuthal correlations on the forward rapidity gap width in pPb collisions at sNN\sqrt{s_\mathrm{NN}} = 8.16 TeV

This paper investigates the dependence of two-particle azimuthal correlations on the forward rapidity gap width in 8.16 TeV pPb collisions to determine if collective flow signatures persist in events enriched with photon-lead and pomeron-lead interactions, comparing the results against previous measurements and modern event generators.

Explaining the B→Kμ+μ−B \to K\mu^+\mu^- Anomaly in the Left-Right Inverse Seesaw Model

This paper demonstrates that the Left-Right Inverse Seesaw model can naturally explain the B→Kμ+μ−B \to K\mu^+\mu^- anomaly by generating a specific negative shift in the Wilson coefficient ΔC9\Delta C_9 while suppressing ΔC10\Delta C_{10} through a non-decoupling charged-scalar/heavy-neutrino box mechanism, all while satisfying stringent flavor and collider constraints.

Machine Learning Enhanced Detection of Higgs Chain Decays in Vector Boson Fusion

This paper demonstrates that advanced Deep Learning methodologies applied to low-level calorimeter data can achieve a statistical significance of approximately 4.5σ in detecting heavy CP-even Higgs boson chain decays (h2→h1h1→bbˉbbˉh_2 \to h_1h_1 \to b\bar b b\bar b) produced via Vector Boson Fusion within the Next-to-Minimal Supersymmetric Standard Model at the LHC with 300 fb−1^{-1} of integrated luminosity.

Comparisons of triple-differential cross sections for quasielastic-like νμ\nu_\mu-hydrocarbon interactions using ⟨Eν⟩∼\langle E_\nu\rangle \sim 3~GeV versus ∼\sim 6~GeV beams in MINERvA

This MINERvA study compares triple-differential cross sections for quasielastic-like νμ\nu_\mu-hydrocarbon interactions in 3 GeV and 6 GeV beams to test neutrino interaction models, revealing discrepancies that indicate an overestimation of final-state interactions for protons and charged pions in current simulations.

Proton High-Order Cumulants in Au+Au Collisions at High Baryon Density from JAM with a Centrality-Independent Framework

This study utilizes the JAM model and a novel Centrality-Independent Genuine Cumulant Analysis (CIGAR) framework to systematically analyze higher-order proton cumulants in Au+Au collisions at high baryon densities, providing a dynamic non-critical baseline essential for the search for the QCD critical point.

Search for single production of a vector-like B' quark decaying to a top quark and a W boson in the single-lepton final state in proton-proton collisions at s\sqrt{s} = 13 TeV

The CMS collaboration presents a search for the single production of a vector-like B' quark decaying to a top quark and a W boson in proton-proton collisions at 13 TeV using 138 fb−1^{-1} of data, which sets the most stringent limits to date on the production of narrow-width singlet B' quarks with masses between 0.8 and 1.23 TeV.

HS3: A Descriptive, Interoperable Serialization Standard for Statistical Models in High-Energy Physics

This paper introduces HS3, a new implementation-agnostic, human-readable, and extensible serialization standard designed to provide a universal, FAIR-compliant format for representing and exchanging statistical models in high-energy physics, thereby overcoming the limitations of existing software-specific formats.
