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 proposes a UV-complete and stable Quintom dark energy model derived from a 5D Non-Perturbative Gauge-Higgs Unification framework on an anisotropic orbifold lattice, which naturally explains the DESI DR2 data through a massive gauge ghost mechanism while avoiding fundamental instabilities and fine-tuning issues.
This paper proposes a novel cogenesis framework based on the type-I Dirac seesaw mechanism, where the out-of-equilibrium decays of heavy vector-like fermions simultaneously generate the baryon asymmetry and an asymmetric dark matter component, allowing for successful cogenesis with dark matter masses ranging from 100 MeV to 39 TeV while remaining testable through neutrino, dark matter, CMB, and gravitational wave observations.
This paper utilizes a five-dimensional holographic model to demonstrate that a time-dependent vacuum angle can induce a delayed deconfinement-to-confinement phase transition with significant supercooling, thereby altering the characteristics of the resulting gravitational wave signals in early universe cosmology.
This paper employs an effective Lagrangian approach combined with one-boson-exchange molecular wave functions to systematically calculate the two-body strong decay widths and branching ratios of single-charm molecular pentaquarks with strangeness , revealing distinctive decay patterns dominated by light meson exchange that serve as testable fingerprints for future experimental searches at LHCb and Belle II.
This paper calculates to light axial vector meson form factors using light cone sum rules within heavy quark effective field theory, providing numerical results up to twist-3 and applying them to predict key observables for charged-current semileptonic decays.
This paper develops a quantum field-theoretic framework that derives a generalized Lindblad master equation to describe neutrino decoherence from momentum-changing scattering in a medium, explicitly linking decoherence parameters to scattering cross sections to probe new physics scenarios including non-standard interactions and dark matter.
This paper presents a novel formalism that resums magnetic field interactions and incorporates finite decay widths of Landau levels to systematically calculate tree-level QED scattering cross sections relevant to magnetar plasma dynamics, with results made available in an open-source Python package.
This paper develops a relativistic quantum field theory based on -deformed Poincaré symmetry that generalizes twisted statistics to quon-like deformations, demonstrating that while purely twisted statistics is experimentally ruled out, specific quon deformations can suppress Pauli-forbidden transitions only if superselection rules are violated, thereby implying an effective breakdown of particle indistinguishability.
This paper demonstrates that loop-level corrections to the leptonic decays of the , , and Higgs bosons provide stronger exclusion limits on heavy, flavor-specific leptophilic gauge bosons than current direct search constraints, offering a complementary probe for new physics at the TeV scale and beyond.
This paper proposes a dark sector framework with a gauge symmetry and vector-like leptons that generates macroscopic Majorana neutrino transition magnetic moments exclusively through chirally enhanced scalar loops, while demonstrating that global phenomenological constraints from charged lepton flavor violation and dark sector searches overwhelmingly dominate and eclipse direct solar neutrino limits.
