B − L model with D5 × Z4 symmetry for lepton mass hierarchy and mixing

Abstract

We propose a gauge B−L model with D5×Z4 for explaining the lepton mass and mixing through the type-I seesaw mechanism. The model can predict the neutrino masses and mixing angles including the Dirac and Majorana CP phases in good agreement with the experimental data. The model also predicts the effective neutrino parameters in highly consistent with the current constraints.
