Han, C G

Using simplified models of CP-noninvariant weak interactions, the induced strong CP violation was calculated. Even in the simple examples considered, the CP-violating phase of a vacuum-to-vacuum transition amplitude differs in general from the phase of the determinant of the quark mass matrix multiplied by the topological charge of the background Yang--Mills field. 13 references.
