Charged lepton flavour violating radiative decays li → lj + γ in see-saw models with A4 symmetry

The charged lepton flavour violating (LFV) radiative decays, mu -> e + gamma, tau -> mu + gamma and tau -> e + gamma are investigated in a class of supersymmetric A(4) models with three heavy right-handed (RH) Majorana neutrinos, in which the lepton (neutrino) mixing is predicted to leading order (LO) to be tri-bimaximal. The light neutrino masses are generated via the type I see-saw mechanism. The analysis is done within the framework of the minimal supergravity (mSUGRA) scenario, which provides flavour universal boundary conditions at the scale of grand unification M-X approximate to 2 x 10(16) GeV. Detailed predictions for the rates of the three LFV decays are obtained in two explicit realisations of the A(4) models due to Altarelli and Feruglio and Altarelli and Meloni, respectively.
