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 investigates the hadronic decay structure of Heavy Neutral Leptons into multi-body final states by proposing a seamless transition between hadronic and partonic descriptions based on invariant mass, highlighting the resulting multi-hadron channels as promising experimental signatures.
This paper proposes a unified effective field theory framework formulated at renormalization group fixed points that successfully connects hadronic spectroscopy, dense baryonic matter, and compact star physics by naturally reproducing parity-doubling spectra and reconciling gravitational-wave constraints with massive neutron stars through chiral-invariant nucleon masses and walking vector couplings.
This paper proposes a minimal leptophobic model with pseudo-Dirac inelastic dark matter that naturally explains the LUX-ZEPLIN 248 keV recoil event while simultaneously satisfying relic density and LHC dijet constraints, predicting specific mediator masses and couplings that can be definitively tested by current and future collider data.
This paper demonstrates that an ultra-slow-roll inflation model with non-Gaussianity can significantly enhance the abundance of primordial black holes to constitute all dark matter while simultaneously suppressing the associated scalar-induced gravitational wave signals, which nonetheless remain detectable by future observatories like LISA.
This paper demonstrates that the complex rotation of supersolids arises from a single irrotational velocity field that naturally separates into a vortex-carrying incompressible component and a density-modulation-driven compressible component, the latter generating a counterflow that explains the system's dual rigid-body and superfluid behavior.
This paper establishes a unified framework connecting Regge factorization and Collins-Soper-Sterman factorization by demonstrating a direct relationship between the Collins-Soper kernel and the Regge trajectory, thereby bridging high-energy and low-transverse-momentum resummation techniques.
Using the AMPT-HC model, this study proposes a phenomenological direct-production mechanism for resonances in Au+Au collisions at GeV to explain how early production and subsequent daughter rescattering in a high-baryon-density medium lead to a predicted increase in the ratio toward central collisions.
This paper derives a Boltzmann equation to precisely calculate the baryon number freeze-out abundance across the electroweak crossover, yielding updated sphaleron conversion factors for both and flavored lepton asymmetries by incorporating higher-order corrections to the partition function and Higgs expectation value.
This paper proposes an flavor symmetry model with generalized CP that successfully reproduces neutrino oscillation data and predicts a testable stochastic gravitational-wave background, establishing a unique falsifiable link between the reactor mixing angle and gravitational-wave observables.
Motivated by the recent LUX-ZEPLIN observation of a single 248 keV nuclear recoil event, this paper proposes an inelastic singlet-doublet fermion dark matter model extended with a scalar triplet, which naturally explains the absence of lower-energy events by suppressing elastic scattering while enabling inelastic transitions and simultaneously generating Majorana neutrino masses via the Type-II seesaw mechanism.
