Abstract
We provide an -based flavor symmetric scenario to accommodate the inverse seesaw mechanism for explaining light neutrino masses and mixing. We find that the lepton mixing, in particular, the tribimaximal mixing pattern and its deviation through nonzero , is originated solely from the flavor structure of the lepton number violating contribution of the neutral lepton mass matrix. Here we discuss in detail how a nonzero value of is correlated with the other parameters in the framework and its impact on the Dirac phase . We also analyze the nonunitarity effects on the lepton-mixing matrix and its implication in terms of the lepton flavor violating decays, etc.
