Pole mass of the W boson at two-loop order in the pure $\overline {MS}$ scheme

  title={Pole mass of the W boson at two-loop order in the pure \$\overline \{MS\}\$ scheme},

I provide a calculation at full two-loop order of the complex pole squared mass of the W boson in the Standard Model in the pure MS-bar renormalization scheme, with Goldstone boson mass effects resummed. This approach is an alternative to earlier ones that use on-shell or hybrid renormalization schemes. The renormalization scale dependence of the real and imaginary parts of the resulting pole mass are studied. Both deviate by about $\pm 4$ MeV from their median values as the renormalization… Expand
