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 demonstrates that the TianQin and LISA gravitational wave detectors can achieve sub-percent precision in reconstructing the new physics scale of the dimension-six Higgs operator model, which generates a strong first-order electroweak phase transition, by combining simulated data analysis, Bayesian inference, and machine learning techniques.
This paper employs a two-flavor Nambu--Jona-Lasinio model coupled with a light-cone quark model to calculate and analyze the in-medium valence quark distribution, electromagnetic form factor, and distribution amplitude of the pion at finite baryon density, comparing the resulting parton distribution functions and their Mellin moments with experimental data, lattice QCD, and theoretical predictions after NLO DGLAP evolution.
This paper demonstrates that realistic spatial variations in Earth's matter density introduce energy-dependent structures in neutrino oscillation probabilities that cannot be captured by path-averaged approximations, thereby creating degeneracies that obscure CP violation measurements and necessitating the use of spatially resolved density profiles in future long-baseline experiment analyses.
The RadioAxion experiment, conducted underground at the Gran Sasso Laboratory using a NaI detector to monitor the 59.5 keV gamma line of Am alpha decay, reports no evidence of periodic modulations indicative of axion dark matter and consequently establishes new constraints on the axion decay constant for masses between and eV.
This paper establishes a comprehensive theoretical framework for open quantum systems coupled to scale-invariant "unparticle" environments, deriving exact non-Markovian dynamics and identifying a rich phase structure of decoherence and thermalization transitions governed by the scaling dimension , with applications ranging from critical quantum magnets and inflationary cosmology to high-energy astrophysical neutrinos.
This paper demonstrates that future solar-neutrino coherent scattering measurements in direct-detection experiments can uniquely probe sterile-neutrino mixing parameters with and , offering complementary constraints to existing long-baseline and atmospheric searches.
This paper employs a finite-volume formalism incorporating left-hand-cut effects from one-pion exchange to analyze lattice QCD data at the SU(3)-symmetric point, revealing that these effects produce a mild but statistically significant impact on the binding energy of the -dibaryon compared to standard Lüscher quantization methods.
This paper demonstrates that collapsing domain walls generically develop robust cuspidal edge and vertex singularities, a phenomenon predicted by Nambu-Goto and eikonal approximations and confirmed by full field theory simulations, which has significant implications for localized energy density and potential phenomenological effects.
This paper systematically classifies Zee models incorporating non-invertible symmetries to identify viable candidates consistent with experimental data, with a detailed numerical analysis of a representative benchmark model yielding specific predictions for neutrino observables and charged lepton flavor violation.
This paper investigates how Yukawa screening in a Bose-Einstein condensate system suppresses infrared kinetic relaxation, thereby broadening the resulting Bose-star density profile and systematically delaying condensation timescales compared to standard Newtonian gravity.
