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 presents a spectator model calculation of thirteen transverse-momentum-dependent gluon distributions in a tensor-polarized deuteron, providing analytical expressions and numerical results that reveal non-negligible effects potentially accessible in future experiments.
This paper details the mathematical framework and numerical implementation for computing the elliptic three-loop Feynman integrals required for the hadronic vacuum polarization calculation in chiral perturbation theory, enabling fast and accurate evaluation for arbitrary complex photon virtualities.
This paper proposes a minimal one-loop radiative framework for generating Dirac neutrino masses by introducing a scalar leptoquark and non-invertible Ising fusion rules, which alleviates Yukawa hierarchies, realizes a radiative type-I seesaw mechanism, and offers rich, testable phenomenology across various flavor and precision observables.
This paper demonstrates that Calabi-Yau and complete elliptic integrals do not contribute to conservative gravitational scattering observables at the fifth post-Minkowskian order because the specific ultraviolet singular structures required to generate the necessary logarithmic terms are absent in the classical limit.
This paper investigates axion dark matter signals from neutron star populations, finding that while wider-angle searches outside the Galactic Centre lack competitive sensitivity, the collective signal from the Galactic Centre population offers detection potential comparable to that of individual magnetars, justifying continued searches for both.
This paper presents a unified model for single-pion production across photon, electron, pion, and neutrino interactions that integrates vector and axial-vector form factors for nucleon resonances up to 2 GeV with non-resonant backgrounds to provide a robust framework for analyzing nucleon structure and constraining uncertainties for future accelerator-based neutrino experiments.
This paper proposes a model utilizing vector-like quarks and scalar messengers with hierarchical vacuum expectation values to explain the quark mass hierarchy and generate the CKM matrix independently of fermion masses, thereby addressing the Standard Model's inability to account for flavor structure.
This paper proposes a more realistic method for estimating the gravitational lensing probability of binary black hole mergers in AGN disks by using a mismatch threshold relative to signal-to-noise ratio, revealing that the detection probability for LIGO-Virgo-KAGRA O3 runs is several times higher than previous Einstein-criterion-based estimates.
This paper calculates the pion valence parton distribution function using a spectral function approach with phenomenological Light-Front wave functions, revealing that the observed intermediate-x behavior and limit are driven by a highly virtual cluster carrying most of the momentum with minimal residual mass, thereby linking the PDF's peak characteristics directly to its analytic behavior at .
This paper presents a comprehensive global fit within the HEPfit framework that constrains Standard Model parameters and dimension-6 SMEFT Wilson coefficients by simultaneously analyzing electroweak, Drell-Yan, Higgs, top, and flavour observables while consistently incorporating leading-order scale evolution and considering both and flavour symmetry limits.
