DOWNLOAD EBOOKThe measurements of the mass of the W boson (M{sub W}) and of the top quark (M{sub t}) are important for three reasons: (i) these masses represent fundamental parameters of the Standard Model; (ii) they determine the coupling between the top quark and the Higgs boson, the coupling being proportional to M{sub t}2/M{sub W}2; and (iii) radiative corrections relate the masses of the W, top quark and the Higgs boson: an accurate measurement of M{sub W} and M{sub t} would provide a constraint on the Higgs mass (M{sub H}). We present here the measurements obtained by the CDF and D0 collaborations corresponding to the so-called Run I of data-taking (1992-95, (almost equal to) 100 pb−1 each) at the Tevatron (p{bar p} collisions, (square root)s = 1.8 TeV). In addition we report on the improvements expected for these measurements in the current run (so-called Run IIa) which, having just started (March 2001), is expected to collect about 2 fb−1 by the year 2004.
