====== TTP02-21 Two-Loop Bosonic Electroweak Corrections to the Muon Lifetime and M_Z-M_W Interdependence ====== The two-loop electroweak bosonic correction to the muon lifetime and the M_W-M_Z interdependece is computed using analytical methods of asymptotic expansion. Combined with previous calculations this copmletes the full two-loop correction to $\Delta r$ 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 mass from 100 to 1000 GeV. |**A. Onishchenko, O.
