Abstract

In this paper we consider the production of top quark pairs close to threshold and compute the dependence on the Higgs boson mass to order αα_s. This requires the evaluation of the matching coefficient of the vector current to two-loop level and the inclusion of Higgs mass dependent operators in the non-relativistic effective theory. For Higgs boson masses below 200 GeV moderate contributions to the top quark mass and the peak cross section are observed. We also provide additional information to the on-shell wave function renormalization which is relevant for the matching coefficient.
