Lepton flavour violating processes in an S_3-symmetric model
Abstract
A variety of lepton flavour violating effects related to the recent discovery of neutrino oscillations and mixings is here systematically discussed in terms of an S_3-flavour permutational symmetry. After presenting some relevant results on lepton masses and mixings, previously derived in a minimal S_3-invariant extension of the Standard Model, we compute the branching ratios of some selected flavour-changing neutral current processes (FCNC) as well as the contribution of the exchange of neutral flavour-changing scalar to the anomaly of the magnetic moment of the muon. We found that the minimal S_3-invariant extension of the Standard Model describes successfully masses and mixings, as well as, all flavour changing neutral current processes in excellent agreement with experiment.
