Abstract

Triple gauge boson couplings are measured from W-pair events recorded by the OPAL detector at LEP at centre-of-mass energies of 183 - 209 GeV with a total integrated luminosity of 680 pb(-1). Only CP-conserving couplings are considered and SU(2) x U(1) relations are used, resulting in four independent couplings, k(gamma), g(1)(z), lambdagamma and g(5)(z). Determining each coupling in a separate fit, assuming the other couplings to take their Standard Model values, we obtain k(gamma) = 0.88(-0.08)(+0.09), g(1)(z) = 0.987 (-0.033),(+0.034) lambda(gamma) = -0.060(-0.033)(+0.034) and g(5)(z) = -0.04(-0.12)(+0.13), where the errors include both statistical and systematic uncertainties. Fits are also performed allowing some of the couplings to vary simultaneously. All results are consistent with the Standard Model predictions.
