Search for Anomalous ZZgamma and Zgammagamma couplings in the process e+e- -> Zgamma at LEP
Abstract
We search for anomalous trilinear gauge couplings in the ZZgamma and Zgammagamma 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- -> Zgamma.
