Mass limit for light flavon with residual Z3 symmetry
Mass limit for light flavon with residual Z3 symmetry
We present a modified Altarelli and Feruglio A 4 model where an additional A 4 singlet-prime flavon is introduced. In this model, non-zero θ 13 is given by this additional A 4 singlet-prime flavon which breaks tri-bimaximal mixing. In the framework of the supersymmetry with U(1) R symmetry, we obtain …
