Charged Lepton Flavour Violating Radiative Decays ${\ell }_i\to {\ell }_j+\gamma$ in See-Saw Models with $A_4$ Symmetry

C. Hagedorn, E. Molinaro, S. T. Petcov

The charged lepton flavour violating (LFV) radiative decays, $\mu \to e+\gamma$, $\tau \to \mu +\gamma$ and $\tau \to e+\gamma$ are investigated in a class of supersymmetric $A_4$ models with three heavy righ…
