Generalised μ-τ symmetries and calculable gauge kinetic and mass mixing in U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ models
Abstract Extensions of the standard model with a U(1) gauge symmetry contain gauge invariant kinetic mixing, sin χ, and gauge non-invariant mass mixing, δM 2, between the hypercharge and the new gauge boson Z ′. These represent a priori incalculable but phe- nomenologically important parameters of t...
