The complex pole mass of the top quark is presented at full two-loop order inthe Standard Model, augmenting the known four-loop QCD contributions. The inputparameters are the MS-bar Yukawa and gauge couplings, the Higgs self-coupling,and the Higgs vacuum expectation value (VEV). Here, the VEV is defined as theminimum of the full effective potential in Landau gauge, so that tadpolesvanish. This is an alternative to earlier results that instead minimize thetree-level potential, resulting in a VEV that is gauge-fixing independent butaccompanied by negative powers of the Higgs self-coupling in perturbativeexpansions. The effects of non-zero Goldstone boson mass are eliminated byresummation. I also study the renormalization scale dependence of thecalculated pole mass.
