Abstract

We search for anomalous ZZ gamma and Z gamma gamma couplings with the L3 detector at LEP, The analysis is based on the study of the process e(+) e(+) --> Z gamma at center-of-mass energies in the range 161 GeV < root s < 183 GeV. No evidence for anomalous effects is found. Limits at the 95% confidence level are set on the values of the eight possible anomalous couplings. Depending on the type of coupling new physics scales below 213 GeV to 1083 GeV are excluded. (C) 1998 Elsevier Science B.V. All rights reserved.
