The One-zero Textures of Majorana Neutrino Mass Matrix and Current Experimental Tests

arXiv:1108.4010 · doi:10.1103/PhysRevD.85.113011

Abstract

We carry out a complete and systematic study of all the possible one-zero textures for the neutrino mass matrix in light of the recent neutrino oscillation data which hint to a relatively large non-vanishing value for the smallest mixing angle (). We find that all the six possible one-zero textures are able to accommodate the experimental data, with five cases allowing also for non-invertible mass matrices. We present symmetry realizations for all the one-zero singular and non-singular patterns in type-I and type-II seesaw mechanism schemes.
