SCOTOGENIC A₄ NEUTRINO MODEL FOR NONZERO θ₁₃ AND LARGE δ_{<font>CP</font>}

Abstract

Assuming that neutrinos acquire radiative seesaw Majorana masses through their interactions with dark matter, i.e. scotogenic from the Greek "scotos" meaning darkness, and using the non-Abelian discrete symmetry A 4 , we propose a model of neutrino masses and mixing with nonzero θ 13 and necessarily large leptonic CP violation, allowing both the normal and inverted hierarchies of neutrino masses, as well as quasi-degenerate solutions.
