摘要：

We compute the complete leading-log terms of the next-to-next-to-next-to-leading-order corrections to potential NRQCD. As a by-product we obtain the leading logs at O(m alpha(s)(5)) in the heavy quarkonium spectrum. These leading logs, when Lambda(QCD) <<m alpha(s)(2), give the complete O(m alpha(s)(5)ln alpha(s)) corrections to the heavy quarkonium spectrum. (C) 1999 Published by Elsevier Science B.V.
