  The complex pole mass of the top quark is presented at full two-loop order in
the Standard Model, augmenting the known four-loop QCD contributions. The input
parameters 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 the
minimum of the full effective potential in Landau gauge, so that tadpoles
vanish. This is an alternative to earlier results that instead minimize the
tree-level potential, resulting in a VEV that is gauge-fixing independent but
accompanied by negative powers of the Higgs self-coupling in perturbative
expansions. The effects of non-zero Goldstone boson mass are eliminated by
resummation. I also study the renormalization scale dependence of the
calculated pole mass.
