Permuted charged lepton correction in the framework of dirac seesaw

A Dirac neutrino mass model is proposed, based on an extended group structure of SU(2)L⊗U(1)Y⊗A4⊗Z3⊗Z10 with the Dirac Type I seesaw mechanism. This work explores the impact of parametrization and permutation in the charged lepton diagonalizing matrix, driven by free parameters in the charged lepton sector, on the predictions of observable parameters. Some interesting consequences on the neutrino mass hierarchies, mixing angles and the Dirac CP phase are observed. The scalar sector is also analyzed in detail, with a brief discussion of its phenomenological implications.
