Lepton Flavour

AbstractWe study the charged lepton flavour violation in a popular neutrino mass model with $$A_4$$ A 4 discrete symmetry. This symmetry requires the presence of multiple Higgs doublets in the model and it also dictates the flavour violating Yukawa couplings of the additional neutral scalars of the model. Such couplings lead to the decays of the neutral mesons, the top quark and the $$\tau $$ τ lepton into charged leptons of different flavours at tree level. The $$A_4$$ A 4 symmetry of the model leads to certain characteristic signatures in these decays. We discuss these signatures and predict the rates for the most favourable charged lepton flavour violating modes.
