AbstractWe investigate a general structure of lepton mixing matrix resulting from the SUF(3) gauge family model with an appropriate vacuum structure of SUF(3) symmetry breaking. It is shown that the lepton mixing matrix can be parametrized by using the Wolfenstein parametrization method to characterize its deviation from the tri-bimaximal mixing. A general analysis for the allowed leptonic CP-violating phase delta(e) and the leptonic Wolfenstein parameters lambda(e), A(e), rho(e) is carried out based on the observed lepton mixing angles. We demonstrate how the leptonic CP violation correlates to the leptonic Wolfenstein parameters. It is found that the phase Se is strongly constrained and only a large or nearly maximal leptonic CP-violating phase vertical bar delta(e)vertical bar similar or equal to 3 pi/4 similar to pi/2 is favorable when lambda(e) > 0.15. In particular, when taking lambda(e) to be the Cabibbo angle lambda(e) similar or equal to lambda similar or equal to 0.225, a sensible result for leptonic Wolfenstein parameters and CP violation is obtained with A(e) = 1.40, rho(e) = 0.20, delta(e) similar to 101.76 degrees, which is compatible with the one in quark sector. An interesting correlation between leptons and quarks is observed, which indicates a possible common origin of masses and mixing for the charged leptons and quarks. (C) 2014 The Authors.
