Connecting nonzero θ13, Dirac CP phase and leptogenesis through spontaneous CP violation

We have analyzed a Type-I+II seesaw scenario to generate neutrino masses and mixing in a A(4) based flavor symmetric framework. The Standard Model (SM) particle content is extended by three singlet right handed neutrinos, an additional higgs triplet along with few SM singlet flavon fields. In this set-up, the pure type-I contribution to the neutrino mass matrix exhibits a tribimaximal (TBM) of lepton mixing where the triplet contribution generates theta(13). Complex vev of one flavon provides a unique source of spontaneous CP violation. Here it turns out that the triplet contribution provides a common source for theta(13), Dirac CP phase (delta) and CP violation required for leptogenesis.
