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 Standard Model extension incorporating degenerate vector-like quarks and a single right-handed neutrino to simultaneously generate neutrino masses, ensure electroweak vacuum stability up to the Planck scale, and achieve successful Higgs inflation consistent with current observational data.
This paper establishes the first exact correspondence between Einstein-scalar-Maxwell theory and gauged Skyrme-Maxwell-Einstein models, enabling the transfer of electrovacuum solution-generating techniques to construct new exact solutions with nonvanishing baryonic charge, including a rotating configuration where baryonic charge quantization enforces a quantization of the Kerr rotation parameter.
This paper refutes a recent proposal that the strong CP problem can be avoided by a specific order of limits in the path integral, demonstrating through exactly solvable quantum mechanical models on a ring that this procedure fails to reproduce the correct physical energy spectrum.
This paper presents a systematic study of atmospheric neutrino-antineutrino discrimination in large liquid-scintillator detectors by analyzing event characteristics such as inelasticity and neutron multiplicity, thereby establishing a foundation for determining the neutrino mass ordering through oscillation studies.
This paper formulates out-of-equilibrium jet momentum broadening in QCD effective kinetic theory using a moment expansion to explicitly derive a leading-order correction to the spatial broadening tensor controlled by the medium's shear-stress tensor, thereby establishing a direct link between kinetic theory and event-by-event viscous hydrodynamic simulations for heavy-ion collisions.
This paper investigates minimal Majoron dark matter within a Type-I seesaw framework, determining that while the mass is generally bounded by MeV without fine-tuning, successful thermal leptogenesis with two right-handed neutrinos favors an ultra-light mass below eV produced via the misalignment mechanism.
This paper presents a deep learning-assisted framework for extracting Generalized Parton Distributions (GPDs) by combining experimental data with ab-initio lattice quantum chromodynamics (LQCD) results to advance the understanding of proton structure.
This paper derives gravitational waveforms for charged compact binaries in Einstein-scalar-Maxwell theories, demonstrating how scalar and vector charges induce dipole radiation and phase modifications characterized by a single parameter , which is constrained by binary pulsar observations and applicable to black hole, neutron star, and exotic compact object systems.
This paper presents a study demonstrating that the Future Circular Collider electron-positron (FCCee) operating at with an integrated luminosity of 10.8 ab could achieve a 95% confidence level upper limit of 0.15% on the branching ratio of invisible Higgs decays by analyzing the production mode with boson decays into electron-positron, muon-antimuon, and hadronic jets.
This paper establishes that the trace of the spin correlation matrix is a basis-invariant quantity for two-fermion production via single mediator exchange at lepton colliders, enabling the determination of spin-analyzing powers, the reconstruction of spin correlations to probe Bell non-locality (specifically in production at BESIII), and the exploration of new physics beyond the Standard Model.
