Description

Preliminary electroweak measurements from the LEP Collaboration from data taken at the Z0 resonance are presented. Most of the results presented are based on a total data sample of 12 x 106 recorded Z0 events which included data from the 1993 and 1994 LEP runs. The Z0 resonance parameters, including hadronic and leptonic cross sections and asymmetries, τ polarization and its asymmetry, and heavy-quark asymmetries and partial widths, are evaluated and confronted with the predictions of the Standard Model. This comparison incorporates the constraints provided by the recent determination of the top-quark mass at the Tevatron. The Z0 resonance parameters are found to be in good agreement with the Standard Model prediction using the Tevatron top-quark mass, with the exception of the partial widths for Z0 decays to pairs of b and c quarks
