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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes that three-body forces are definitively necessary in specific three-body hadronic systems with certain charge parities, demonstrating through contact-range potential calculations that while these forces play a minor role in the system, they are crucial for determining whether the system forms a bound state.
This paper proposes the first scotogenic model with gauged lepton number that is spontaneously broken to a residual symmetry, thereby generating tiny Dirac neutrino masses at one loop while simultaneously providing a stable scalar dark matter candidate consistent with current experimental constraints and predicting observable charged lepton flavor violating decays.
This paper models the multi-messenger signatures of Superluminous Supernovae powered by millisecond magnetars, demonstrating that the scenario successfully explains the high-energy gamma-ray detection of SN 2017egm by Fermi LAT and predicts that stacking analyses with future observatories could achieve a detection of neutrinos from such events within a decade.
This paper presents a classically scale-invariant no-scale Standard Model completion that successfully accounts for new physics constraints and recent cosmological data (Planck/BICEP/Keck/ACT) by proposing a two-stage inflationary scenario involving a slow-roll phase, a radiation-dominated era, and a subsequent thermal phase.
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.
