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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper demonstrates that the minimal majoron framework can simultaneously explain neutrino masses, dark matter, and the matter-antimatter asymmetry by identifying a cosmologically viable parameter space where high-scale thermal leptogenesis constrains the majoron abundance and couplings, making the scenario testable by future X- and gamma-ray telescopes.
This study demonstrates through spherical core-collapse supernova simulations of various progenitor masses that flavor conversion can either enhance or suppress explosion success by altering neutrino heating efficiency, depending critically on whether the conversion occurs near the gain region or the neutrino decoupling region, regardless of the progenitor's mass or compactness.
This paper employs chiral perturbation theory to calculate the next-to-leading order renormalized magnetic masses and decay constants for the meson octet in a uniform magnetic field, revealing that neutral kaon masses remain unaltered while charged meson masses and all decay constants increase monotonically, with results validated by newly constructed low-energy theorems.
This paper proposes that the thermodynamic Gibbs entropy of quark-gluon plasma is preserved during hadronization by being converted into the quantum entanglement entropy of confined partons within hadrons, a hypothesis supported by three independent estimates showing that a proton's internal entanglement entropy matches the magnitude of the QGP entropy from which it formed.
This paper demonstrates that pronounced spectral fringes in Schwinger pair production can emerge from smooth, carrier-free single-lobe electric pulses due to a turning-point dominance transition where subleading contributions interfere, a mechanism confirmed in both QED and Dirac materials like epitaxial graphene.
This paper presents the first rigorous collinear factorization calculation of the twist-3 gluon contribution to the single transverse-spin asymmetry in production, demonstrating that the -even gluon distribution drives a sizable asymmetry at RHIC and LHC energies and offering a unique probe for the three-dimensional motion of gluons within the proton.
This paper argues that while weak triplet models can theoretically decouple neutrino magnetic moments from neutrino masses, achieving a naturally observable enhancement requires delicate parameter tuning, and in extended scenarios, the two quantities become intrinsically linked again.
This paper utilizes the PACIAE and DCPC models to compare and production in 7 TeV $pp$ collisions, revealing significant differences in transverse momentum spectra between compact tetraquark and molecular states that can serve as experimental criteria for distinguishing their internal structures.
This paper presents a redetermination of the proton's light flavor sea quark distributions using NNLO global analyses of HERA and ATLAS data, revealing an unexpected asymmetry where the anti-up quark distribution exceeds the anti-down quark distribution in the momentum fraction range , leading to a Gottfried Sum Rule value that significantly differs from previous experimental results.
This paper proposes the rare Standard Model Higgs decay as a probe of Higgs interactions, calculating its branching ratio of approximately and demonstrating that it can be observed with high significance at both the High-Luminosity LHC and the ILC using multivariate analysis techniques.
