英文摘要	U(1) global symmetry to solve the strong CP problem could be a remnant of multi-U(1) symmetries from QCD and hidden strong dynamics. Both Peccei-Quinn U(1) and dynamical U(1) are described uniformly, based on which we classify various mixed two-U(1) models to solve both strong CP and quality problems. We propose a moose diagram method with different fermion assignments to directly read relations between CP phases, which illustrate how the strong CP problem is solved in terms of cancellation between CP phases. In two-axion models, we find that the lightest axion is still the same as a QCD axion in the infrared region, while a one-axion model with Z(2) symmetry enhances the axion mass spectrum. Our discussions can be extended to multiaxion cases.
