利用渐近展开的解析方法，计算了双回路电弱玻色子对μ子寿命和毫微米-毫微米相互依赖关系的修正。结合先前的计算，这完成了对标准模型中Δr的完整双环校正。在希格斯玻色子质量从100到1000 GeV的范围内，双环玻色子修正对w -玻色子质量预测的偏移不超过1 MeV。
The two-loop electroweak bosonic correction to the muon lifetime and the MW–MZinterdependence is computed using analytical methods of asymptotic expansion. Combined with previous calculations this completes the full two-loop correction to Δr 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.
