A viable $$L_e-L_\mu $$ L e - L μ model with $$\mu \rightarrow e$$ μ → e violation

Abstract We extend the Standard Model gauge group by $$U(1)_{L_e-L_\mu }$$ U ( 1 ) L e - L μ and introduce two scalars, a doublet and a singlet, that are charged under this new group and have lepton flavour violating couplings. Since in this model $$\mu \rightarrow e$$ μ → e processes can only be me...
