摘要：

The two-loop electroweak bosonic correction to the muon lifetime and the M-W-M-Z interdependence is computed using analytical methods of asymptotic expansion. Combined with previous calculations this completes the full two-loop correction to Deltar in the Standard Model. The shift to the prediction of W-boson mass due to two-loop bosonic corrections does not exceed 1 MeV for the range of the Higgs boson mass from 100 to 1000 GeV. (C) 2002 Elsevier Science B.V.
