Abstract
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 roots = 18 9 GeV with the OPAL detector, The invariant mass distributions from 970 W+W - --> qqqq and 1118 W+W- --> qq(l)v(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 Gamma (W) = 2.0 9 +/- 0.18 (stat,) +/- 0.09 (syst,) GeV, The results are combined with prev ious OPAL results from 78 pb(-1) of data recorded with roots from 161 to 18 3 GeV, to obtain: M-W = 80.432 +/- 0.066 (stat,) +/- 0.035 (syst,) GeV, Gam ma (W) = 2.04 +/- 0,16 (stat,) +/- 0.09 (syst.) GeV, The consistency of the direct measurement of Mw with that inferred from other measurements of ele ctroweak parameters provides an important test of the Standard Model of ele ctroweak interactions.
