摘要
This letter describes a measurement of one of the anomalous triple gauge boson couplings using the first data recorded by the OPAL detector at LEP2. A total of 28 W-pair candidates have been selected for an integrated luminosity of 9.89+/-0.06 pb(-1) recorded at a centre-of-mass energy of 161 GeV. We use these data to place constraints upon the coupling parameter alpha(W phi). We analyse the predicted variation of the total cross-section for all observed channels and the distribution of kinematic variables in the semileptonic decay channels. We measure alpha(W phi) to be -0.61(-0.61)(+0.73)+/-0.35, which is consistent with the Standard Model expectation of zero. (C) 1997 Published by Elsevier Science B.V.
