The magic of four zero neutrino Yukawa textures

High Energy Physics - Phenomenology 2017-08-23 v1

Abstract

Four is the maximum number of texture zeros allowed in the Yukawa coupling matrix of three massive neutrinos. These completely fix the high scale CP violation needed for leptogenesis in terms of that accessible at laboratory energies. μτ\mu\tau symmetry drastically reduces such allowed textures. Only one form of the light neutrinos mass matrix survives comfortably while another is marginally allowed.
