A minimal model of spontaneous CP violation with the gauge group SU(2)sub(L)xSU(2)sub(R)xU(1)sub(B-L)

We propose and analyze a minimal model of spontaneous CP violation with the gauge symmetry SU(2)sub(L) x SU(2)sub(R) x U(1)sub(B-L). We find that the 'isoconjugate relation' of Mohapatra and Pati is no longer valid in this model even for the four-quark case. However, due to a dynamical effect, all three of the main superweak predictions (etasub(+-)=eta00, etasub(+-0)=eta000 and etasub(+-0)=etasub(+-)) are approximately true to better than 1%. For the six-quark-case, we find the Kobayashi-Maskawa phase is calculable and small so that its presence does not appreciably change the phenomenology of the model. (orig.)
