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.

The paper introduces \textsc{Albert}, a neuro-symbolic AI framework that successfully rediscovered the Standard Model and autonomously predicted the top quark's mass using only legacy LEP data, demonstrating a rigorous, hallucination-free approach to discovering new physics.
This paper addresses the challenges of extracting 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.
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.
This paper demonstrates that a multivariate XGBoost analysis significantly enhances the discovery potential for singly produced vector-like bottom quarks decaying via the exotic () channel at the High-Luminosity LHC, extending the mass reach up to 1.6 TeV with 3 ab of data even in the presence of substantial systematic uncertainties.
This paper presents the first non-perturbative determination of the model-independent QCD contribution to the axion-photon coupling using continuum extrapolated lattice simulations, yielding a precise value that enables updated constraints on axion models to guide future experimental strategies.
This study employs a physics-informed machine learning framework to determine field-dependent Nambu-Jona-Lasinio model parameters, specifically the running coupling constant and quark anomalous magnetic moment, by fitting lattice QCD data to successfully reproduce the inverse magnetic catalysis effect in magnetized QCD matter.
Using chiral perturbation theory, this study identifies and characterizes two distinct types of baryonic vortices in rotating nuclear matter, demonstrating that finite-size causality constraints regularize the energy divergence of global vortices, thereby establishing them as viable topological excitations that compete energetically with local vortices.
This paper proposes a flavor-deconstructed gauge theory where embedding the Standard Model in separate gauge groups for each fermion family naturally yields sequential dominance, offering a viable explanation for the flavor structure of both neutrinos and charged leptons.
This paper presents the derivation of two-loop leading-colour scattering amplitudes for bottom-quark pair production in association with a Higgs boson () at the LHC, focusing on top-Yukawa contributions within the massless bottom and heavy-top approximations, and expresses the finite remainder using one-mass pentagon functions with analytically reconstructed rational coefficients.
This paper utilizes Born-Oppenheimer Effective Field Theory and lattice QCD calculations to demonstrate that the near-degeneracy and specific decay patterns of the hidden-bottom tetraquarks and arise from the degeneracy of their underlying light degrees of freedom, identified as and adjoint mesons.
