Top-quark pole mass

Abstract

The top quark decays more quickly than the strong-interaction time scale, ${\text{lqcd}}^{-1}$, and might be expected to escape the effects of nonperturbative QCD. Nevertheless, the top-quark pole mass, like the mass of a stable heavy quark, is ambiguous by an amount proportional to $\text{lqcd}$.
