LFV in Models with A4 Flavour Symmetry

The approximated tri-bimaximal mixing (TBM) observed in the ν oscillations is a particular feature of a class of models characterized by the spontaneously broken horizontal flavour symmetry A4. In this paper, it is presented an analysis on the predictions of these models for relevant low-energy observables. In an effective operator approach, these effects are dominated by dim-6 operators, suppressed by the scale M of new physics (NP). Indications for M and an upper bound on θ13 of a few percent are found.
