Dirac neutrino mass in a U(1)L model with T7×Z4 symmetry

Abstract

We propose a $U{\left(1\right)}_L$ model with $T_7\times Z_4$ symmetry for generating Dirac neutrino mass matrix texture. The Dirac neutrino mass matrix hints for a realistic lepton mixing pattern where the explicit relations between the Yukawa-like couplings and the observed neutrino oscillation parameters are established. The Yukawa-like couplings in the charged-lepton sector are expressed in terms of three charged lepton masses while the Yukawa-like couplings in the neutrino sector are expressed in terms of neutrino oscillation parameters. The considered model is satisfied for both normal and inverted neutrino mass hierarchies and for both lower and higher octants in the light of the recent experimental data.
