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 presents the calculation of planar two-loop four-point Feynman integrals with full electron mass dependence for radiative return processes, overcoming analytical complexities involving nested square roots and elliptic geometries to provide stable numerical evaluations essential for next-to-next-to-leading order QED predictions.
This paper proposes a unified, falsifiable closed-form spectral template for gravitational waves generated during a cosmological stasis epoch, which allows future detectors like BBO and DECIGO to verify or rule out any constant-equation-of-state cosmology by testing whether measured spectral tilt and amplitude step data align with a specific consistency curve.
This paper demonstrates that the "swift memory burden" of black holes, which can vastly exceed the information content of their progenitors and significantly alter gravitational wave frequencies during mergers, serves as a probe into both the fundamental mechanisms of black hole information storage and their formation history.
This paper investigates a minimal fermion-portal scalar dark matter model constrained by current experimental limits, demonstrating that its viable parameter space can be effectively probed through the discovery of lightest charged vector-like fermions at future 3 TeV and 10 TeV muon colliders via clean signatures.
This paper employs a model-independent, two-fluid approach with agnostic equations of state to demonstrate that dark matter admixed neutron stars form either extended halos or compact cores depending on the dark matter mass, leading to distinct observational signatures that constrain the dark matter fraction to less than 11% using current data.
This paper introduces a physics-informed posterior learning method that leverages geometric-optics consistency to distinguish lensed gravitational wave signals from unrelated multiple mergers, significantly improving detection efficiency and lowering the required signal-to-noise ratio for identifying lensed events in dense catalogs.
This paper proposes using the attenuation of pre-supernova neutrino fluxes in large-volume detectors like KamLAND, JUNO, and Super-K to derive upper limits on dark matter-neutrino scattering cross sections, offering a unique MeV-energy probe that complements post-b supernova constraints and tests early-universe dark matter models.
This paper presents a relativistic study using the Bethe-Salpeter equation to predict the exclusive production cross sections of P-wave charmonia ( and ) via two virtual photons in electron-positron annihilation at GeV, yielding benchmark results of order fb that exhibit a smooth power-law energy dependence and a hierarchy determined by meson wave function overlaps.
This paper proposes an extended DFSZ axion model incorporating right-handed neutrinos and new scalars, demonstrating that the Peccei-Quinn transformation becomes independent of the Higgs mixing angle and that the resulting coupling modifier for the trilinear Higgs self-coupling remains consistent with current experimental constraints for specific mass and vacuum expectation value parameters.
This paper proposes a novel mechanism for achieving a naturally light composite Higgs by identifying it as a protected collective eigenmode of the strong sector's scalar kernel, characterized by specific diagnostic parameters and a microscopic sensitivity of order one, which is realized through a rank-one locking invariant and universal vectorlike bridge fermions that lift the Higgs mass only at joint two-spurion order.
