Contribution

It provides comprehensive analysis of LEP2 data on fermion pair production and derives constraints on theories beyond the Standard Model.

Findings

Constraints on new physics models

Precise measurements of fermion production cross sections

Abstract

Preliminary results on $e^+ e^- \to f \bar{f}$, $f=e, \mu, \tau, q$, including all LEP2 data are discussed. Good agreement is found with the Standard Model up to the highest energies. Limits on possible new physics are extracted.
