LEP precision electroweak measurements from the Z0 resonance
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
