Abstract

Using a data sample of 57 pb -1 recorded at a centre-of-mass energy of 183 GeV with the OPAL detector at LEP, 282 W + W - → qq̄qq̄ and 300 W + W - → qq̄lv̄ l candidate events are used to obtain a measurement of the mass of the W boson, M w = 80.39 ± 0.13(stat.) ± 0.05(syst.) GeV, assuming the Standard Model relation between M w and T W . A second fit provides a direct measure of the width of the W boson and gives T W = 1.96 ± 0.34(stat.) + 0.20(syst.) GeV. These results are combined with previous OPAL results to obtain M w = 80.38 ± 0.12(stat.) + 0.05(syst.) GeV and T w = 1.84 ± 0.32(stat.) ± 0.20(syst.) GeV. © 1999 Published by Elsevier Science B.V.
