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 A1 and A2 and interesting constraints on the neutrino parameters have been obtained. It is shown that the octant of θ23 and the quadrant of the Dirac-type CP-violating phase δ can be used to lift this degeneracy.
