Neutrino phenomenology via Type-(I+II) seesaw in the $U(1)_{L_e-L_\mu}$ model

We show how, L_e-L_\mu L e − L μ gauged symmetry is used as the Standard Model (SM) extension with the type (I+II) seesaw mechanism for neutrino mass generation. The particle content of this model involves three extra right handed neutrinos, one scalar triplet and one singlet with the SM spectrum. W...

Summary:We show how, L_e-L_\mu L e − L μ gauged symmetry is used as the Standard Model (SM) extension with the type (I+II) seesaw mechanism for neutrino mass generation. The particle content of this model involves three extra right handed neutrinos, one scalar triplet and one singlet with the SM spectrum. We discuss about lepton flavour violating decays \mu → e\gamma μ → e γ , \tau \to \mu \bar \mu\mu τ → μ μ ‾ μ and anomalous magnetic moment of muon.
