μ子寿命和M_Z-M_W相互依赖的双圈玻色子电弱修正

Two-Loop Bosonic Electroweak Corrections to the Muon Lifetime and M_Z-M_W Interdependence

A. Onishchenko, O. Veretin

摘要:

用渐近展开的解析方法计算了μ子寿命和M_W-M_Z相互依赖的双圈电弱玻色子修正。结合先前的计算,这将完整的双环路校正完成到标准模型中的$Δr$。由于双环玻色子修正,对W玻色子质量预测的偏移在希格斯粒子质量从100到1000 GeV的范围内不超过1 MeV。

英文摘要:

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 $Δr$ 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 mass from 100 to 1000 GeV.
