Abstract
We resum the leading ultrasoft logs of the singlet and octet static QCD pot entials within potential NRQCD. We then obtain the complete three-loop reno rmalization group improvement of the singlet QCD static potential. The disc repancies between the perturbative evaluation and the lattice results at sh ort distances are slightly reduced. (C) 2000 Published by Elsevier Science B.V.
