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 computes the flavor-separated chiral-odd nucleon tensor form factors and their resulting monopole, dipole, and quadrupole moments using light-cone QCD sum rules, revealing new exact analytical relations between quark flavors and providing numerical predictions for the transverse spatial deformation of the nucleon's and quarks.
This paper proposes a UV-complete extension of the Standard Model that naturally generates a strongly coupled dark QCD sector with mixed representations, SM-like flavor structures, and exotic global symmetries, while systematically analyzing the diverse portals connecting this dark sector to the visible universe.
This paper numerically investigates the non-equilibrium evolution of a quantum scalar field following a mass quench in a finite-size system, revealing that periodic boundary conditions cause counter-propagating wave fronts to interfere at half the system size, resulting in a strong disturbance of the effective mass.
This paper calculates the dominant bosonic two-loop virtual electroweak corrections to parity-violating Møller scattering at low energies, finding that these contributions shift the electron effective weak charge by 0.3% and reducing the theoretical uncertainty from purely bosonic sources to approximately 0.1% for the MOLLER experiment.
This paper demonstrates that interpreting charged-lepton flavor violation limits as probes of -sector new physics requires simultaneously accounting for both dimension-6 renormalization-group running and dimension-8 operator mixing, as neglecting either mechanism leads to significant errors in constraining the underlying Wilson coefficients.
This paper proposes a scalar-extended model featuring a trilinear scalar interaction that generates the necessary mass splitting for inelastic dark matter scattering, offering a viable explanation for the 248 keV excess observed by the LUX-ZEPLIN experiment while satisfying current phenomenological constraints.
This paper proposes a novel cosmological model featuring cooling QCD axions with a number density six times that of cosmic microwave background photons to resolve the Hubble tension by effectively doubling the baryon density required by late-universe SH0ES observations while maintaining consistency with early-universe Planck data.
This paper investigates gravitational spectroscopy of ultracold neutrons within the framework of Very Special Relativity, finding that while leading-order effects preserve standard equivalence principles, next-to-leading order corrections introduce time-dependent anisotropic signatures that allow for the derivation of preliminary constraints on Lorentz-violating parameters using current experimental sensitivities.
This paper establishes a general effective theory framework for detecting light portal dark matter in high-threshold experiments by systematically incorporating finite momentum transfer effects, nucleon matrix elements from lattice QCD, and nuclear responses via the relativistic Fermi gas model, while demonstrating its application to spin-1 and spin-2 mediator models that address the core-cusp problem.
This paper establishes a theoretical framework for electron-positron single-inclusive annihilation incorporating twist-4 contributions, demonstrating through a spectator model that these higher-twist effects, particularly the fragmentation function , improve the description of low-energy production data from BESIII.
