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 nonzero $θ_{13}$ , and allows for deviations from maximal mixing. The phenomenology of this model is reexamined in the light of recent hints for nonzero $θ_{13}$ .
