New magic textures of Majorana neutrinos

The magic texture is one of the successful textures of the flavor neutrino mass matrix for Majorana neutrinos. In this paper, it turns out that two new types of magic textures are also consistent with neutrino oscillation experiments, observation of cosmic microwave background radiation, and neutrinoless double beta decay experiments. The connection be- tween these new magic textures and the leptogenesis scenario for the origin of the baryon asymmetry of the Universe is also discussed.This presentation is based on 'Yuta Hyodo and Teruyuki Kitabayashi,Prog.
