Title Spontaneous CP violation & Baryon asymmetry
Abstract Spontaneous CP violation such as the Nelson-Barr mechanism is an attractive solution to the strong CP problem. In this talk, first, I discuss supersymmetry with gauge mediation as an attractive scenario to suppress the correction to theta-bar. Second, baryon asymmetry in the universe can be obtained from Affleck-Dine baryogenesis by flat-direction associated with heavy vector-like quark.
