چکیده
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 ∆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 boson mass from 100 to 1000 GeV.

The relationship between MS and pole masses of the vector bosons Z and W is calculated at the two-loop level in the Standard Model. We only consider the purely bosonic contributions which represents a gauge invariant subclass of diagrams. All calculations were performed in the linear Rξ gauge with three arbitrary gauge parameters utilizing the method of asymptotic expansions. The results are pr...
