Z' reservation at LEP2

We consider the possibility that one extra Z\equiv Z' exists with arbitrary mass 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 lept...

description We consider the possibility that one extra Z\equiv Z' exists with arbitrary mass 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 future e^+e^- colliders that is completely independent of the values of the Z' mass and couplings. This selects a certain region in the 3-d space of the deviations that is \underline{characteristic} of the model (Z' "reservation"). As a specific and relevant example, we show the picture that would emerge at LEP2 under realistic experimental conditions.

We show that, in such a situation, a functional relationship is generated between the deviations from the SM values of three leptonic observables of two-fermion production at future e + e − colliders that is completely independent of the values of the Z ′ mass and couplings. This selects a certain region in the 3-d space of the deviations that is characteristic of the model ( Z ′ “reservation”).
