Heavy Charged Leptons in an $SU(3{)}_L\otimes U(1{)}_N$ Model

Abstract

We consider an $SU(3{)}_L\otimes U(1{)}_N$ model for the electroweak interactions which includes extra charged leptons which do not mix with the known leptons. These new leptons couple to $Z^0$ only through vector currents. We consider constraints on the mass of one of these leptons coming from the $Z^0$-width and from the muon $(g-2)$ factor. The last one is less restrictive than the former.
