Probing Anomalous Gauge Boson Couplings at LEP

Abstract

We bound anomalous gauge boson couplings using LEP data for the $Z\rightarrow {\overline f} f$ partial widths. We use an effective field theory formalism to compute the one-loop corrections resulting from non-standard model three and four gauge boson vertices. We find that measurements at LEP constrain the three gauge boson couplings at a level comparable to that obtainable at LEPII.Comment: Latex file with 3 uuencoded figures, 13 pg, Invited talk given by S.D. at the Joint U.S.-Polish Workshop on Physics from the Planck Scale to the Electroweak Scale, Sept 21-24, 1994, Warsaw, Poland and by G.V. at the 1er.
