Abstract: (Elsevier)

The mass and width of the W boson are determined in e + e − collisions at LEP using 183 pb −1 of data recorded at a centre-of-mass energy s =189 GeV with the OPAL detector. The invariant mass distributions from 970 W + W − →qqqq and 1118 W + W − →qqℓ ν ℓ candidate events are used to measure the mass of the W boson, M W =80.451±0.076 (stat.)±0.049 (syst.) GeV. A direct measurement of the width of the W boson gives Γ W =2.09±0.18 (stat.)±0.09 (syst.) GeV. The results are combined with previous OPAL results from 78 pb −1 of data recorded with s from 161 to 183 GeV, to obtain: M W =80.432±0.066 (stat.)±0.045 (syst.) GeV, Γ W =2.04±0.16 (stat.)±0.09 (syst.) GeV. The consistency of the direct measurement of M W with that inferred from other measurements of electroweak parameters provides an important test of the Standard Model of electroweak interactions.
