Abstract
The process $e+e- ->$ W+W-gamma is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of 188.6GeV, corresponding to an integrated luminosity of 176.8pb$^{-1}$. Based on a sample of 42 selected W+W- candidates containing an isolated hard photon, the W+W-gamma cross section, defined within phase-space cuts, is measured to be: sigma_WWgamma = 290 +/- 80 +/- 16 fb, consistent with the Standard Model expectation. Including the process e+e- -> nu nu gamma gamma, limits are derived on anomalous contributions to the Standard Model quartic vertices W+W- gamma gamma and W+W-Z gamma at 95% CL: -0.043 GeV^-2 a_0/Lambda^2 0.043 GeV^-2 0.08 GeV^-2 a_c/Lambda^2 0.13 GeV^-2 0.41 GeV^-2 a_n/Lambda^2 0.37 GeV^-2.
