Z' Reservation at LC2000

Abstract

We consider the possibility that one extra ZZZ\equiv Z' exists with a mass of more then two TeV and fermion couplings that do not violate (charged) lepton universality. We show that, in such a situation, a functional relationship is generated between the \underline{deviations} from the SM values of three leptonic observables of two-fermion production at LC 2000 that is completely independent of the values of the ZZ' mass and couplings. This selects a certain region in the 3-d space of the deviations (ZZ' "reservation") that is \underline{characteristic} of the model and that would have no observable intersection with analogous regions corresponding to other interesting models of new physics.
