Using a broadband radio-frequency atomic magnetometer, researchers conducted a search for axion-like dark matter in the mass range of to , finding no significant signals but establishing improved upper limits on ALP-proton couplings and complementary constraints on ALP-neutron and ALP-electron interactions.
This paper combines high-energy collision data analyzed via the PHSD transport approach with cosmological and astrophysical constraints to establish comprehensive exclusion limits on the parameter space of a kinetically mixed dark photon model coupled to stable dark matter.
This paper derives the Polyakov loop kinetic term from first principles in SU(3) Yang-Mills theory and demonstrates that while this term drastically alters gravitational-wave predictions for confinement transitions, it has a negligible impact on chiral transition dynamics within the PNJL framework.
This paper generalizes neutrino energy density in the early universe using Tsallis nonextensive statistics and, by confronting the resulting deformation of the effective number of neutrinos with CMB, BAO, and BBN data, establishes stringent constraints on the Tsallis parameter such that is limited to approximately at 95% and 99% confidence levels.
This paper proposes a non-minimally coupled running curvaton model that successfully accommodates DESI's preference for dynamical dark energy with phantom crossing while preserving early-universe predictions and potentially alleviating the Hubble tension.
This paper investigates how quark portal interactions involving a light singlet fermion allow for testing baryon number violation through LHC missing energy searches, displaced vertex signatures, and rare meson or top quark decays, thereby constraining new physics scales up to 11 TeV and narrowing viable mesogenesis models for future high-luminosity facilities.
This paper resolves the DFSZ axion domain wall problem by demonstrating how the global structure of symmetry groups and non-invertible chiral symmetries enforce domain wall stability, suggesting that UV theories with small-instanton-induced symmetry breaking can naturally resolve the issue while producing distinct gravitational wave signatures.
This review paper outlines the physics prospects of proposed Super Tau-Charm Factories, highlighting their unique capabilities in high-luminosity electron-positron collisions to advance precision tests of the Standard Model, explore CP violation, study tau and charm properties, and investigate nonperturbative QCD phenomena.
This paper presents a systematic two-loop analysis of axion effective field theory within the BMHV scheme, demonstrating how evanescent operators arising from the non-anticommuting nature of violate naive Ward identities and deriving the necessary finite renormalization to restore consistency and correctly recover the axial anomaly.
This paper demonstrates that the mathematical equations governing the masses of glueballs in the holographic QCD hardwall model are identical to those describing the vibrations of a classical circular drumhead, thereby providing a compelling motivation for undergraduate students to study drumhead dynamics as a gateway to understanding advanced particle physics.
