摘要：

The presently most accurate prediction for the W-boson mass in the standard model is obtained by combining the complete two-loop result with the known higher-order QCD and electroweak corrections. The numerical impact of the different contributions is analyzed in detail. A simple parametrization of the full result is presented, which approximates the full result for M-W to better than 0.5 MeV for 10 GeVless than or equal toM(H)less than or equal to1 TeV if the other parameters are varied within their combined 2sigma region around their experimental central values. The different sources of remaining theoretical uncertainties are investigated. Their effect on the prediction of M-W is estimated to be about 4 MeV for M(H)less than or similar to300 GeV.
