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 employs supervised machine learning to evaluate the distinguishability of four neutron star matter models using macroscopic and oscillation-related quantities, revealing that while certain scenarios can be separated under controlled assumptions, others exhibit intrinsic degeneracies due to fundamental similarities in their effective equations of state.
This paper proposes that the behavior of the effective potential in Higgs-portal scalar singlet systems, characterized by a topologically stable non-simple singularity with Milnor number , can be comprehensively mapped and experimentally verified through high-precision measurements of Higgs couplings and gravitational waves, ensuring that any viable strong first-order electroweak phase transition will be detected or ruled out by 2040.
This paper presents a five-dimensional holographic construction of the QCD axion that clarifies its relationship with the meson and anomalies, while demonstrating that solving the axion quality problem requires significant axion compositeness and a physical state predominantly residing in the bulk gauge field.
This paper proposes a novel mechanism where a large matter-antimatter asymmetry in Dirac fermions generates finite-temperature radiative corrections that destabilize cosmological domain walls, offering a unique pathway to probe the asymmetry's magnitude and generation temperature through future gravitational wave observations while potentially explaining baryon asymmetry, dark matter, and neutrino asymmetry.
This paper investigates how Planck-scale quantum-gravity corrections, modeled via a dimension-5 operator in a (3+1) four-flavor neutrino framework, induce significant deviations in the atmospheric mixing angle and alter the entanglement entropy evolution of neutrino oscillations, thereby offering a sensitive probe for Planck-scale physics.
This paper demonstrates that Nelson-Barr models utilizing vector-like quark doublets offer a phenomenologically viable solution to the strong CP problem by leveraging an accidental symmetry to delay leading contributions to until three loops, thereby naturally suppressing hadronic CP violation.
This paper investigates the collider phenomenology of feebly interacting dark matter produced via a spin-2 portal, demonstrating that machine learning-enhanced searches at the High-Luminosity LHC can effectively probe cosmologically viable freeze-in parameter space through Vector Boson Fusion channels.
The paper proposes a non-redundant, ordered, and family-unified quark flavor structure derived from hierarchical quark masses that offers a potential replacement for the Standard Model's unclear Yukawa interactions by revealing new insights into both the mass matrix and CKM mixing.
This paper proposes using gravitational tidal effects, such as apsidal motion and orbital precession, to constrain the internal chemical and structural compositions of low-eccentricity, short-period pulsar companions, thereby shedding light on their unique formation histories.
This paper argues that the non-trivial topological structure of the Euclidean Schwarzschild black hole manifold supports non-trivial electromagnetic configurations that, through the electromagnetic -term, induce -asymmetric Hawking radiation manifested as an imbalance between left- and right-polarized photons.
