Phenomenological Analysis of Hybrid Textures of Neutrinos

Understand

We present a comprehensive phenomenological analysis of the allowed hybrid textures of neutrinos.

• Out of a total of sixty hybrid textures with one equality between the elements of neutrino mass matrix and one texture zero only twenty three are found to be viable at 99% C.L.
• whereas the earlier analysis found fifty four to be viable.
• We examine the phenomenological implications of the allowed hybrid textures including Majorana type CP-violating phases, 1-3 mixing angle and Dirac type CP-violating phase, $\delta$.
