It is presented an analysis on lepton flavour violating transitions, leptonicmagnetic dipole moments and electric dipole moments in a class of modelscharacterized by the flavour symmetry A4 x Z3 x U(1)_FN, whose choice ismotivated by the approximate Tri-Bimaximal mixing observed in neutrinooscillations. A low-energy effective Lagrangian is constructed, where theseeffects are dominated by dimension six operators, suppressed by the scale M ofnew physics. All the flavour breaking effects are universally described by thevacuum expectation values of a set of spurions. Two separate cases, asupersymmetric and a general one, are described. An upper limit on the reactorangle of a few percent is concluded.
