Phenomenology of minimal seesaw model with S4 Symmetry

We show that a modification of tribimaximal (TBM) mixing matrix accommodating non-zero mixing angle q13 and CP violation can be achieved in a minimal seesaw model with discrete symmetry S4. This model is very predictive and the undetermined parameters are a common Dirac Yukawa coupling, lightest heavy Majorana neutrino mass and a Majorana phase in the light neutrino sector. The unknown parameters are shown to be constrained through leptogenesis by imposing the recent experimental neutrino data. Based on the constraints obtained from neutrino data and leptogenesis, we predict the branching ratios of the lepton flavor violating processes li !l jg as well as the effective neutrino mass of neutrinoless double beta decays.
