CPviolation in seesaw models of quark masses

CP phenomenology in ‘‘seesaw’’ models of quark masses is shown to parallel that of the usual left-right-symmetric models with the additional advantage that it provides a natural solution to the strong CP problem. For the case where the third-generation mixing parameter $V_{\mathrm{ub}}$ is extremely small, the neutral-Higgs-boson interactions lead to ε’/ε≃${10}^{\mathrm{-}3}$ and the electric dipole moment of the neutron $d_n$≃${10}^{\mathrm{-}25}$ e cm. Smallness of the neutrino masses is understood as a two-loop effect.
