Abstract

The O(\alpha \alpha_s) contribution to the relationship between the MS- and the pole-mass of the t-quark propagator within the Standard Model is reviewed. At the same order also the corrections to the top-Yukawa coupling is discussed. We furthermore present the exact analytic expression for the gaugeless limit.

Keywords
