Description
We present new results for the matching coefficient between the QCD and the non-relativistic QCD (NRQCD) vector current. The matching coefficient constitutes one of the missing ingredients for a complete NNNLO theory prediction of top-quark pair production at a future linear collider. Furthermore, the matching coefficient is an important building block for the analysis of heavy quarkonia, which will allow for the precise determination of the bottom-quark mass from sum rules.
