What can solve the strong CP problem?
Abstract Three possible strategies have been advocated to solve the strong CP problem. The first is the axion, a dynamical mechanism that relaxes any initial value of the CP violating angle θ ¯ $$ \overline{\theta} $$ to zero. The second is the imposition of new symmetries that are believed to set θ...
