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 investigates the magnetic counterpart of the Uehling correction in QED by calculating vacuum polarization effects around a classical point-like magnet, revealing induced paramagnetic currents, a quantum-level breaking of the symmetry between electric and magnetic dipole fields, and resulting contributions to the hyperfine structure of hydrogen-like atoms.
This paper presents a unified formalism to clarify the isospin limit and estimate the Standard Model CP asymmetries in , , and decays to , predicting values of approximately , , and respectively.
This contribution systematically investigates the phenomenology of fermionic top partners in exotic color-sextet representations within composite Higgs models, derives their decay patterns, and establishes current LHC exclusion limits up to 2.5 TeV as well as the projected sensitivity of the HL-LHC near 3 TeV.
This work derives pressure-energy equations of state for the nucleon from gravitational form factors and the conservation of the energy-momentum tensor, revealing a fundamental balance between pressure-induced static pressure (associated with condensate depletion and confinement) and traceless dynamic pressure, while simultaneously demonstrating that the same relations also apply to vortices in type-II superconductors and the cosmological constant in the CDM model.
This article summarizes compelling evidence for new Higgs bosons at approximately 95 GeV and 152 GeV and suggests that these electroweak-scale excesses—particularly in the two-photon channel and in specific production modes—could resolve tensions in the Standard Model and explain phenomena such as dark matter and neutrino masses.
This article examines how the high neutrino fluxes generated during the collapse of supermassive stars undergo flavor transformations via MSW resonances and collective oscillations, whereby, depending on the neutrino mass hierarchy, electron-neutrino fluxes can be exchanged with muon/tau flavors, significantly affecting energy deposition and nucleosynthesis in the outer layers of the star.
This work investigates the production of - and -bound states in decays using the Bethe-Salpeter framework and the one-boson-exchange model, finding that while -bound states exist across all coupling sets, -bound states are restricted to specific parameter ranges, with predicted branching ratios in the range of to .
This article examines the realization of spontaneous CP violation within a supersymmetric theory, demonstrating how this resolves the strong CP problem, generates the CKM phase, and successfully explains the baryon asymmetry of the universe via the Affleck-Dine mechanism, while simultaneously predicting a measurable electric dipole moment for the neutron.
This article proposes two TeV-scale singlet-doublet dark matter models (Majorana and Dirac) that simultaneously explain the origin of radiative neutrino masses, the baryon asymmetry of the universe via leptogenesis, and the dark matter relic density, while offering testable signatures for collider experiments and cosmology.
This contribution presents updated theoretical predictions for the lifetimes of all weakly decaying doubly heavy baryons ($bb$, $cc$, $bc$) as well as the meson by incorporating higher-order QCD corrections, comparing various mass schemes, and establishing specific lifetime hierarchies for different ground-state spin configurations.
