The three loop relation between the \bar {MS} and the pole quark masses
Kirill Melnikov🇺🇸 · Timo van Ritbergen🇩🇪
Abstract
The analytic relation between the \bar {MS} and the pole quark masses is computed to O(\alpha_s^3) in QCD. Using this exact result, the accuracy of the large \beta_0 approximation is critically examined and the implications of the obtained relation for semileptonic B decays are discussed.
