摘要

The preliminary LEP2 data on e~+e~– → l~+l~– scattering are analyzed to establish a model-independent search for the signals of virtual states of the Abelian Z boson. The recently introduced observables make it possible to pick up uniquely the Abelian Z signals in these processes. The mean values of the observables are in accordance with the Z existence. However, the accuracy of the experimental data is deficient to detect the signal at more than a 1 C.L. The results of other model-independent fits and further prospects are discussed.
