The anomalous magnetic dipole moment (MDM) and electric dipole moment (EDM) of the τ lepton are vital probes for new physics beyond the Standard Model. Utilizing azimuthal angular asymmetry as an innovative tool in ultraperipheral collisions (UPCs), we achieve unprecedented precision in studying these properties. This approach, driven by the highly linear polarization of coherent photons,...

The strong charge-parity (CP) problem has been a long-standing problem in particle physics since 1976, illustrating the small CP-violation phase in quantum chromodynamics (QCD). The axion, based on the Peccei-Quinn mechanism, is the most popular solution to the problem. In this paper, we propose an alternative solution based on the three-zero texture of quark mass matrices without additional...
