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.

This paper proposes a precision measurement using a 3 mW tunable diode laser and a 1 T permanent-magnet assembly in a Mach-Zehnder interferometer to detect axion-photon conversion, aiming to determine the gravitational constant with a 38 ppb accuracy—a 600-fold improvement over current standards—by measuring the axion Compton frequency.
This paper investigates the rotation of the polarization plane of electromagnetic waves caused by strong, spatially varying axion fields in neutron star polar caps, deriving both perturbative and non-perturbative solutions to demonstrate that such rotation requires axion inhomogeneity and predicting that the resulting nanosecond-scale gap-filling times could be detectable with atomic clocks.
This paper demonstrates that entanglement entropy serves as a sensitive probe for CPT-violating Planck-scale physics in neutrino oscillations by revealing a distinct asymmetry between neutrino and anti-neutrino entropy profiles that is controlled by Majorana phases.
This paper presents an indirect determination of the top-quark pole mass as 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 while refitting PDFs to properly correlate uncertainties across various ATLAS and CMS measurements.
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 lepton decays, thereby enabling the exclusion of superluminal entanglement signaling theories.
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.
This paper demonstrates that interactions between ultra-light dark matter scalars and Standard Model or dark sector particles can significantly alter the misalignment mechanism, thereby modifying the expected amplitude of scalar oscillations and the resulting late-time dark matter abundance.
This paper investigates the sensitivity of the FASER and SHiP experiments to dark photons and U(1) 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.
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.
