Measurement of the W and top mass at the Tevatron: Results and perspectives

PDF Version Also Available for Download.

Description

The 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}{sup 2}/M{sub W}{sup 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 ... continued below

Description

The 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}{sup 2}/M{sub W}{sup 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, {approx} 100 pb{sup -1} each) at the Tevatron (p{bar p} collisions, {radical}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{sup -1} by the year 2004.
