1205.0075 (Hajime Ishimori et al.)

New Simple A_4 Neutrino Model for Nonzero θ_{13} and Large
δ_{CP}
   [PDF]

Hajime Ishimori, Ernest Ma
In a new simple application of the non-Abelian discrete symmetry $A_4$ to charged-lepton and neutrino mass matrices, we show that for the current experimental central value of $\sin^2 2 \theta_{13} \simeq 0.1$, leptonic CP violation is necessarily large, i.e. $|\tan \delta_{CP}| > 1.3$.
