Abstract

We search for anomalous trilinear gauge couplings in the ZZγ and Zγγ vertices using data collected with the L3 detector at LEP at a centre-of-mass energy √s=189 GeV. No evidence is found and limits on these couplings and on new physics scales are derived from the analysis of the process e+e−→Zγ.
