Abstract

Abstract The possible existence of neutral triple ZZZ, ZZγ and Zγγ and quartic ZZγγ gauge boson couplings is investigated. Based on data collected at LEP2 at centre-of-mass energies up to 208 GeV no evidence has been found for such couplings. Preliminary limits for neutral triple gauge couplings as obtained from the combination of the LEP experiments are presented.
