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 novel quantity derived from gravitational wave amplitude and frequency derivatives to extract dark matter density profiles around black holes, enabling multi-wavelength observations to probe dark sector properties and constrain primordial black hole origins.
This study utilizes the PACIAE 4.0 model, which incorporates both color-singlet and color-octet NRQCD contributions alongside cluster collapse and -hadron decays, to successfully simulate inclusive production in proton-proton collisions at 5.02, 7, and 13 TeV and provide a quantitative analysis of the relative contributions and rescattering effects across various production mechanisms.
This paper argues that the Kerr-Schild and twistorial double copy prescriptions are equivalent for a broad class of self-dual vacuum solutions, a claim demonstrated through elementary null Lorentz transformations and illustrated with the self-dual Kerr-Taub-NUT spacetime.
This paper investigates the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond-the-Standard-Model mediators within the JLab polarized positron program, highlighting how the observable's unique zero crossing in the Standard Model provides a clean, background-free opportunity to significantly extend search ranges for scalar and vector new physics scenarios.
This paper utilizes Ultra-Relativistic Quantum Molecular Dynamics (UrQMD) simulations to demonstrate that the three-dimensional two-pion emission source in intermediate-mass Ar+Sc collisions at SPS energies is well-described by Lévy-stable distributions, thereby establishing a theoretical baseline for future femtoscopy measurements in such systems.
This paper proposes a minimal extension of the Leptogenesis framework that links the generation of the baryon asymmetry and asymmetric dark matter through heavy Majorana neutrino decays, offering a testable TeV-scale mechanism that connects neutrino masses to observable direct detection signals.
This paper establishes strict quantitative conditions and demonstrates via simulation that a mesoscopic spinor Bose-Einstein condensate of approximately 370 spins near the Lipkin-Meshkov-Glick critical point can exhibit classically forbidden temporal correlations, specifically through an exponentially suppressed Landau-Zener error rate and a Leggett-Garg inequality violation (K_3 ~ 1.32), both robust against realistic dephasing due to emergent collective symmetry and dynamical phase alignment.
This paper demonstrates that a Weyl-flat null origin of inflation is compatible with current observations by establishing it as an asymptotic universality class for single-field models, which yields a viable phenomenological framework with realistic spectral indices and tensor-to-scalar ratios.
This study utilizes PYTHIA simulations of proton-proton collisions at 14 TeV to demonstrate that including inverse Compton scattering events in quark-gluon scattering analyses results in a moderate, constant increase in particle yield without significantly broadening transverse momentum spectra, thereby validating pp collisions as a reliable baseline for investigating energy redistribution in dense QCD media.
This paper introduces `fermionic_amplitudes.m`, a Mathematica package that computes tree-level scattering amplitudes for arbitrary numbers of gauge bosons and massless fermions in pure non-supersymmetric gauge theories by expressing distinct-flavour amplitudes as linear combinations of single-flavour components derived from supersymmetric Yang-Mills theory, while providing explicit numeric colour tensors for cross-section calculations.
