Search for anomalous $ZZ\gamma$ and $Z\gamma\gamma$ couplings in the process $e^+e^- \to Z\gamma$ at LEP

We search for anomalous trilinear gauge couplings in the ${\rm ZZ}\gamma$ and ${\rm Z}\gamma\gamma$ vertices using data collected with the L3 detectorat LEP at a centre--of--mass energy $\sqrt{s}=189$ GeV. No evidence is found and limits on these couplings and on new physics scales are derived from...

Description
Summary:We search for anomalous trilinear gauge couplings in the ${\rm ZZ}\gamma$ and ${\rm Z}\gamma\gamma$ vertices using data collected with the L3 detectorat LEP at a centre--of--mass energy $\sqrt{s}=189$ GeV. No evidence is found and limits on these couplings and on new physics scales are derived from the analysis of the process ${\rm e}^{+}{\rm e}^{-} \rightarrow {\rm Z} \gamma$.
