Abstract

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- recorded at a centre-of-mass energy of 161 GeV. We use these data to place constraints upon the coupling parameter α. 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 αwφ to be -0.61+0.73 -0.61 ±0.35, which is consistent with the Standard Model expectation of zero.

N2 - 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- recorded at a centre-of-mass energy of 161 GeV. We use these data to place constraints upon the coupling parameter αwφ. 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 αwφ to be -0.61+0.73 -0.61 ±0.35, which is consistent with the Standard Model expectation of zero.
