We analyze the cross section ofe+e−→τ+µ−within the frameworks of SM and itsZ′ extension. The theoretical prediction of the SM on the total cross section is suppressed by the tiny neutrino masses. On the other hand, the contributions fromZ′ to the cross section are enhanced drastically because of the tree level FCNC couplings amongZ′ and leptons.
