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 presents the most precise determination of the primordial helium-4 mass fraction to date, demonstrating that combining this new measurement with primordial deuterium data and cosmic microwave background observations yields a baryon density and effective number of neutrino species consistent with the Standard Model of particle physics and standard cosmology.
This paper proposes that the recently detected ultra-high energy neutrino event KM3-230213A likely originates from the diffuse neutrino flux produced by a population of luminous fast blue optical transients (LFBOTs) powered by newly formed magnetars.
This paper investigates the dynamics of a probe massless particle near the horizon of a dyonic AdS-Reissner-Nordström black hole under a harmonic potential, revealing that the extremal black hole limit exhibits a counteracting regulatory role where it enhances chaos at low energies (violating the Lyapunov bound) but suppresses it at high energies, thereby establishing a direct mapping between black hole thermodynamics and microscopic chaos.
This paper proposes a unified KSVZ-type axion model incorporating modular symmetry and a global symmetry to simultaneously explain the origin of radiative Dirac neutrino masses, the strong CP problem, and dark matter, while predicting a massless neutrino and testable signatures for charged lepton flavor violation and axion-photon coupling.
This paper presents a local subtraction scheme that enables the fully numerical integration of real-virtual NNLO QCD corrections for electroweak production by systematically modifying Feynman integrands to achieve local infrared finiteness and gauge symmetry cancellations in momentum space.
This paper employs a nonperturbative Hamiltonian framework using Daubechies wavelets in momentum space to analyze dimensional theory, successfully demonstrating the emergence of a strong-coupling phase transition in the sector.
This paper systematically constructs a complete and finite basis of modular-invariant operators within the Standard Model Effective Field Theory (SMEFT) framework by implementing distinct flavor symmetries for quarks and leptons, utilizing Hilbert-series techniques to enumerate independent operators up to dimension 7 under holomorphic assumptions, and extending the formalism to non-holomorphic cases to avoid infinite proliferation while preserving key physical structures like the Weinberg operator.
This paper utilizes the worldline formalism to present a unified one-loop calculation of photon-graviton mixing in an electromagnetic field, identifying a previously overlooked tadpole diagram that contributes to the amplitude but does not affect magnetic dichroism, while also extending the analysis to include scalar loops and electric field components.
This paper proposes a refined search strategy targeting a narrow axion mass window of 78.6 to 79.6 micro-eV (18.99–19.01 GHz) using a resonant cavity detection scheme based on the inverse Primakoff effect, supported by recent simulations and novel experimental designs involving Josephson Parametric Amplifiers and Resonant Tunneling Diodes.
This paper presents the threshold resummation of large logarithms up to NNLL accuracy for on-shell -boson pair production at the LHC, demonstrating that matching these resummed predictions to NNLO fixed-order results significantly reduces scale uncertainties and provides a precise description of the invariant mass distribution in the high-energy regime.
