Implications of a class of neutrino mass matrices with texture zeros for non-zero ${\theta }_{13}$

Abstract

A class of neutrino mass matrices with texture zeros realizable using the group $Z_3$ within the framework of type (I+II) seesaw mechanism naturally admits a non-zero ${\theta }_{13}$ and allows for deviations from maximal mixing. The phenomenology of this model is reexamined in the light of recent hints for non-zero ${\theta }_{13}$.
