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.
