Phenomenology of Two-Texture Zero Neutrino Mass Matrices

Abstract

The generic predictions of two-texture zero neutrino mass matrices in the flavor basis have been examined especially in relation to the degeneracies between mass matrices within a class and interesting constraints on the neutrino parameters have been obtained. It is shown that the knowledge of the octant of ${\theta }_{23}$, the sign of $\cos \delta$ and neutrino mass hierarchy can be used to lift these degeneracies.
