Mixing angles andCPviolation in the SO(10)×U(1)PQmodel

The general considerations of the previous paper are applied to a specific model based on SO(10)×${\mathrm{U}\left(1\right)\mathrm{}}_{\mathrm{PQ}}$. Quark and lepton mass relations are discussed. Weak mixing angles and $\mathrm{CP}$ violation are computed in terms of the top-quark mass and two effective vacuum phase angles. The predictions fall within experimentally allowed limits for a range of variation of these parameters. More precise experimental data will allow a three-parameter fit of our results and lead to predictions on $B$-meson physics, rare decay modes, etc.
