Abstract

We present numerical benchmark solutions for Hermitian Dirac neutrino mass matrices with three texture zeros within the type-I seesaw mechanism. The analysis is to normal ordering (NO) and inverted (IO). The heavy Majorana mass matrix is assumed diagonal, while the Dirac mass matrix is taken Hermitian. Four viable textures in NO are shown to reproduce the neutrino oscillation observables within the $3\sigma$ ranges of the NuFIT global analysis, and three viable textures in IO.
