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 a -symmetric Type-III seesaw model where radiative corrections lift the vacuum degeneracy to destabilize domain walls, thereby simultaneously explaining neutrino masses, generating the baryon asymmetry via leptogenesis, and predicting a gravitational-wave spectrum potentially detectable by future observatories.
This paper presents a high-bandwidth levitated magnetometer utilizing a double-resonance mode and hybrid ferromagnetic components to achieve a magnetic-field resolution of 0.7 fT, thereby establishing new direct limits on axionlike dark matter in the 40–3000 Hz frequency range that improve upon previous results by over four orders of magnitude.
This paper proposes that quantum-gravitational D-foam effects, which suppress pair creation in atmospheric electromagnetic cascades, could lead to an underestimation of primary cosmic-ray energy and a relative enhancement of muon content, potentially offering a theoretical explanation for the long-standing "muon puzzle" observed by the Auger and Telescope Array collaborations.
This paper proposes an orbital-angular-momentum-resolved extension of small- gluon tomography in hard diffractive dijet deep inelastic scattering, demonstrating that replacing the standard plane-wave lepton current with a twisted wave-packet current enables tunable Bessel projections of the gluon Wigner distribution, thereby revealing a unique normalized projection zero where the elliptic response vanishes despite a finite diffractive rate.
The RAD@home citizen science project discovered a unique, asymmetric bow-and-arrow-shaped radio galaxy in a multi-halo environment, where its distinctive ~560 kpc arc-like structure suggests interaction with a bow shock driven by the host galaxy's supersonic infall.
This paper utilizes the non-negativity of relative entropy in background electromagnetic fields to derive unified constraints on nonlinear electrodynamics effective field theories, demonstrating that this metric serves as a comprehensive diagnostic for both perturbative consistency and non-perturbative stability across various frameworks.
This paper introduces DSWIM, a numerically robust and computationally efficient deterministic framework for calculating warm inflation perturbations that utilizes a physically motivated scaling transformation to resolve ill-conditioning issues, eliminate numerical artifacts, and reconcile discrepancies between stochastic and deterministic methods while preserving accuracy.
This paper argues that the axial U(1) anomaly is not physical and proposes a mechanism wherein the eta and eta' mesons are identified as Nambu-Goldstone bosons, thereby resolving the U(1) problem.
This paper reviews the fundamentals and significance of flavor-diagonal hadronic CP violation in the search for new physics, summarizes recent progress in quantifying its contribution to observables like electric dipole moments and beta decay correlations, and discusses current approaches to solving the strong CP problem without introducing additional fields.
This paper constructs an equation of state for isentropic dark-matter-admixed neutron stars to demonstrate that dark matter accumulation significantly enhances central density and can mimic conformality signatures typically attributed to quark matter in cold stars, driven by a competition between thermal effects and dark sector softening.
