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 investigates how fermionic dark matter interacting with nucleons via a vector mediator () alters the equation of state and structural properties of neutron stars, demonstrating that observational constraints on mass, radius, and tidal deformability can limit vector portal parameters while linking astrophysical findings to terrestrial dark matter searches.
This paper proposes a type III seesaw model within a non-holomorphic modular symmetry framework where Yukawa couplings are fixed at specific modular symmetry points, demonstrating that certain fixed points and their immediate neighborhoods can successfully reproduce observed neutrino oscillation data and the baryon asymmetry of the Universe.
The paper proposes a theoretical framework featuring a duplicated hypercharge that is identical for the Standard Model sector but distinct for a dark sector, thereby simultaneously explaining the origin of neutrino masses and the nature of dark matter.
This paper investigates the viability of natural supersymmetry with mixed axion-axino dark matter, demonstrating that scenarios where the axino is the lightest supersymmetric particle can satisfy dark matter abundance constraints across specific ranges of the Peccei-Quinn scale and axino mass in both DFSZ and KSVZ models, thereby offering a solution to the exclusion of higgsino-like WIMP scenarios by current direct detection limits.
This paper demonstrates that the recently observed need for a right-handed vector boson admixture in neutron decay successfully explains CP-violation effects in neutral meson oscillations (, , , and ) within an extended left-right weak interaction model, suggesting that the nature of CP violation is fundamentally linked to the presence of right-handed currents.
This study systematically investigates the meson-baryon molecular nature of hidden charm pentaquark states and using a coupled-channel framework with heavy quark spin symmetry, revealing that while full symmetry treatment is essential for the system, the system yields similar results with simplified sector splitting, and confirming that the resulting bound states possess characteristic molecular radii between 0.5 and 2 fm.
This paper presents a comprehensive Bayesian MCMC analysis of the meson spectrum using standard and logarithmically modified Cornell potentials to rigorously quantify uncertainties, probe the sensitivity of excited states to confinement forms, and provide updated theoretical predictions for future experimental benchmarks.
This paper proposes a Type I seesaw model with symmetry and soft-breaking terms at the electroweak scale that successfully explains light neutrino oscillation data, identifies the lightest right-handed neutrino as a dark matter candidate via freeze-in, and generates the baryon asymmetry through resonant leptogenesis using only a minimal set of parameters.
This paper derives updated supernova constraints on muon-philic scalars and pseudoscalars by incorporating two-photon couplings from muon triangle loops, revealing that while globular-cluster limits dominate for light masses, supernova 1987A gamma-ray observations and energy-loss arguments impose stringent bounds on heavier masses that challenge the viability of these bosons explaining the muon magnetic-moment anomaly.
This paper demonstrates that in axion monodromy inflation, oscillatory modulations of the potential continuously excite heavy moduli fields, thereby invalidating the conventional single-field approximation and generating detectable cosmological collider signals in the primordial bispectrum that bypass standard Boltzmann suppression.
