Large CP Violation, Large Mixings of Neutrinos and Democratic-type Neutrino Mass Matrix

Kiko Fukuura, Takahiro Miura, Eiichi Takasugi +1

We propose a democratic-type neutrino mass matrix based on $Z_3$ symmetry. This mass matrix predicts the CP violation phase, $\delta =\pi /2$, and the mixing angle between the mass eigensta…
