Phenomenological Implications of a Class of Neutrino Mass Matrices

Abstract

The generic predictions of two-texture zero neutrino mass matrices of class A in the flavor basis have been reexamined especially in relation to the degeneracy between mass matrices of types A_1 and A_2 and interesting constraints on the neutrino parameters have been obtained. It is shown that the octant of ${\theta }_{23}$ and the quadrant of the Dirac-type CP-violating phase $\delta$ can be used to lift this degeneracy.
