Phenomenological implications of a class of neutrino mass matrices Original Research Article

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