Abstract
The W and Z bosons masses, m(W) and m(Z), are measured using samples of W --> ev and Z --> e+e- decays observed in ppBAR collisions at square-root s = 630 GeV. The ratio is found to be m(W)/m(Z) = 0.8813 +/- 0.0036 +/- 0.0019. This gives a value sin2 theta(w) = 0.2234 +/- 0.0064 +/- 0.0033, and in combination with precise m(Z) measurements from LEP yields m(W) = 80.35 +/- 0.33 +/- 0.17 GeV. This result is in good agreement with other experiments, and with the standard model for a top quark mass lighter than 250 GeV.
