Title: Two-loop ultrasoft running of the O(v{sup 2}) QCD quark potentials

Abstract

The two-loop ultrasoft contributions to the next-to-leading logarithmic (NLL) running of the QCD potentials at order v{sup 2} are determined. The results represent an important step towards the next-to-next-to-leading logarithmic (NNLL) description of heavy quark pair production and annihilation close to threshold.
