Abstract

The process e(+)e(-) --> W+W- gamma is studied using the data collected by the L3 detector at LEP. New results, corresponding to an integrated luminosity of 427.4 pb(-1) at centre-of-mass energies from 192 to 207 GeV, are presented. The W(+)W(-)gamma cross sections are measured to be in agreement with Standard Model expectations. No hints of anomalous quartic gauge boson couplings are observed. Limits at 95% confidence level are derived using also the process e(+)e(-) --> nu(nu) over bar gammagamma. (C) 2002 Published by Elsevier Science B.V.
