Lepton flavor models with discrete prediction of theta_{13}

Abstract

We study the lepton flavor models with the flavor symmetry (Z_N \times Z_N \times Z_N)\rtimes Z_3. Our models predict non-vanishing discrete values of \theta_{13} as well as \theta_{12} and \theta_{23} depending on N. For certain values, our models realize the tri-bimaximal mixing angles with \theta_{13}=0. For other values, our models provide with discrete deviation from the tri-bimaximal mixing angles.
