Abstract

We search for anomalous trilinear gauge couplings in the ZZ gamma and Z gamma gamma vertices using data collected with the L3 detector at LEP at a centre-of-mass energy root s = 189 GeV. Na evidence is found and limits on these couplings and on new physics scales are derived from the analysis of the process e(+)e(-) -> Z gamma. (C) 2000 Elsevier Science B.V. All rights reserved.
