We consider the SM extension with additional light real singlet scalar, right-handed neutrino and nonrenormalizable Yukawa interaction for the first two generations. We show that the proposed model can explain the observed (g – 2) muon anomaly. Phenomenological consequenses as flavour violating decays τ → μμμ, μμe, μee are briefly discussed. We also propose the UR(1) gauge generalization of the SM with complex scalar singlet and nonzero right-handed charges for the first two generations.
