Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.

A Determination of the Top Mass from a Global PDF Analysis

This paper presents an indirect determination of the top-quark pole mass as 172.80±0.26172.80 \pm 0.26 GeV by performing a global analysis of parton distribution functions within the NNPDF framework, which incorporates high-precision QCD and electroweak corrections, toponium contributions, and lattice constraints on αs\alpha_s while refitting PDFs to properly correlate uncertainties across various ATLAS and CMS measurements.

Higgs Boson Spookiness: Probing Quantum Nonlocality with Spacetime-Resolved H→τ+τ−H\rightarrow\tau^+\tau^- Decays

This paper proposes that a future precision $ee$ Higgs factory could perform the first spacetime-resolved test of quantum nonlocality in Higgs boson decays by measuring spin correlations between spacelike-separated τ\tau lepton decays, thereby enabling the exclusion of superluminal entanglement signaling theories.

Quark-Mass Dependence of Light-Nuclei Masses from Lattice QCD and Trace-Anomaly Contributions to Nuclear Bindings

This paper presents lattice QCD calculations of light-nuclei masses across various quark masses to establish first-principles constraints on nuclear interactions and reveals that, while quark-mass contributions to binding energy are small and additive, the dominant contribution arises from the gluonic component via the QCD trace anomaly.

Dark photon and U(1)B−L_{B-L} gauge boson from dark Higgs boson decays at FASER and SHiP

This paper investigates the sensitivity of the FASER and SHiP experiments to dark photons and U(1)B−L_{B-L} gauge bosons produced via dark Higgs boson decays, incorporating new single-boson production channels, deriving constraints from current FASER data, and projecting future discovery potential for these models including those with freeze-in sterile neutrino dark matter.

Towards a formalism for ππ\pi\pi scattering from staggered lattice QCD

This paper addresses the challenges of extracting ππ\pi\pi scattering amplitudes from staggered lattice QCD by proposing two complementary approaches: calculating one-loop amplitudes using Rooted Staggered Chiral Perturbation Theory to verify quantization conditions, and generalizing the Lüscher formalism to explicitly incorporate taste-splitting and fourth-rooting effects.

Fermion scattering in a Bose-Einstein condensate

This paper derives the fermion spinors and propagators necessary for calculating scattering rates in a scalar Bose-Einstein condensate background, applying these results to demonstrate how helicity-dependent dispersion relations lead to unique kinematic features, such as Van Hove singularities, with potential applications in cosmic-ray cooling and dark matter interactions.

Probing Heavy Neutral Higgs Bosons via Single Vector-Like Bottom Quark Production at the HL-LHC

This paper demonstrates that a multivariate XGBoost analysis significantly enhances the discovery potential for singly produced vector-like bottom quarks decaying via the exotic B→ϕbB \to \phi b (ϕ→ttˉ\phi \to t\bar{t}) channel at the High-Luminosity LHC, extending the mass reach up to 1.6 TeV with 3 ab−1^{-1} of data even in the presence of substantial systematic uncertainties.
