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 systematically evaluates the sensitivity of four semi-supervised anomaly detection methods to untunable hyperparameters in the search for Beyond the Standard Model physics and proposes a robust, non-parametric permutation test for statistical assessment.
By applying the Hawking Area Theorem, validated through gravitational wave data, as a consistency criterion for black hole entropy corrections, this study derives constraints on the spin-parity and number of Beyond-Standard-Model particle species that may serve as dark matter candidates.
This paper proposes and tests a novel method using AGN reverberation mapping of multiple emission lines to constrain dark matter density profiles around supermassive black holes, finding tentative evidence for a universal profile with a steepness index of while highlighting the need for improved systematic uncertainties in future campaigns.
This study proposes that self-bound hybrid stars characterized by strong phase transitions and large density discontinuities can simultaneously resolve multiple observational tensions regarding the masses, radii, and tidal deformabilities of various compact objects, including anomalous low-mass pulsars, the massive GW190814 secondary, and standard NICER measurements.
This paper presents an updated version of the TGlauberMC Monte Carlo code (v3.3) with improved nuclear density profiles and nucleon substructure treatments to provide precise predictions for initial-state observables and centrality-dependent multiplicity in upcoming oxygen-oxygen, neon-neon, and proton-oxygen collisions at the LHC.
This paper investigates the diquark structure hypothesis of the scalar state by employing QCD light-cone sum rules to calculate transition form factors, branching fractions, and angular observables for the semileptonic decays , ultimately yielding branching fractions on the order of .
This paper develops a vector bundle supermanifold framework with Fermi normal coordinates to geometrically interpret scalar-fermion effective field theories, specifically applying this formalism to the Standard Model Higgs sector to analyze the phenomenological consequences of custodial symmetry violation and field space non-analyticities.
Motivated by recent BESIII measurements, this paper presents the first perturbative QCD analysis of the -hyperon electric dipole moment, deriving a factorization formula that links it to quark dipole interactions and highlighting its unique sensitivity to the strange-quark chromo-electric dipole moment as a complementary probe to the neutron EDM.
These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.
This paper investigates realistic physical termination criteria for cosmic-ray backtracing in the atmosphere, demonstrating that the simplified sharp-boundary approximation should be replaced by altitude-dependent thresholds (at least 50 km for protons and higher for heavy nuclei) determined by the combined effects of Bethe-Bloch energy loss and hard scattering interactions.
