Abstract

A highly predictive neutrino mass matrix texture is proposed. The texture is minimal and carries two interesting correlations. It gives precise and unambiguous answers to almost all the current issues related to observable parameters in neutrino phenomenology. The texture is developed in a framework of type-I + type-II seesaw mechanisms with an extended group structure of $SU(2)_L \times U(1)_Y \times A_4 \times Z_{10} \times Z_{7} \times Z_{3}$.
