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 introduces a generative framework based on denoising diffusion to perform model-independent, non-parametric reconstruction of proton gravitational form factors from sparse and noisy data, enabling robust extraction of chiral low-energy constants and the nucleon D-term across the full kinematic range.
This paper demonstrates that shock-induced density and temperature perturbations in core-collapse supernovae and neutron star mergers can overcome electron mass damping to sustain the chiral plasma instability and generate substantial ohmic heating via the chiral magnetic effect.
This paper generalizes the jet transport coefficient to a Lorentz-covariant diffusion tensor to describe momentum broadening in out-of-equilibrium media, revealing new energy-momentum correlations and demonstrating that non-equilibrium corrections can either enhance or reduce broadening depending on the initial distribution.
This paper presents a parameter-economical, unified quark-diquark effective mass framework calibrated on baryon spectroscopy and meson splittings to systematically predict the spectra of heavy tetraquarks and pentaquarks while naturally incorporating heavy-quark spin and flavor symmetries.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper proposes a covariant orbital-spin decomposed amplitude using massive canonical-spinor variables to streamline partial wave analysis of complex decay chains, a method validated by consistent results in the TF-PWA framework for the decay.
This paper demonstrates that while BPS geodesics with enhanced symmetry remain unchanged in the scattering of multiple Abelian-Higgs vortices, the excitation of massive bound modes introduces forces that significantly deform generic vortex trajectories and enhance chaotic behavior in the final state.
This study demonstrates that self-interacting dark matter models, particularly those with large cross-sections, can explain the diverse dark matter density profiles of Milky Way ultra-faint dwarf galaxies by showing that most have undergone gravothermal collapse accelerated by tidal stripping.
This paper presents significantly improved supernova constraints on CP-even scalars mixing with the Higgs boson by combining updated cooling calculations with new decay-based limits, thereby probing mixing angles down to and Yukawa couplings to , which extends sensitivity by over five orders of magnitude beyond existing collider bounds.
The paper introduces Beyond21, a fast, open-source Python package that provides a unified framework for modeling the Cosmic Dawn and Epoch of Reionization to predict global 21-cm signals and other observables, while enabling flexible exploration of both standard astrophysics and beyond-Standard-Model scenarios like millicharged dark matter.
