Revisiting the texture zero neutrino mass matrices

Abstract

In the light of refined and large reactor mixing angle θ13\theta_{13}, we have revisited the texture three and two zero neutrino mass matrices in the flavor basis. For Majorana neutrinos, it has been explicitly shown that all the texture three zero mass matrices remain ruled out. Further, for both normal and inverted mass ordering, for the texture two zero neutrino mass matrices one finds interesting constraints on the Dirac-like CP violating phase δ\delta and Majorana phases ρ\rho and σ\sigma.
