Abstract

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(mα(s)⁵) in the heavy quarkonium spectrum. These leading logs, when Λ(QCD) << mα(s)², give the complete O(mα(s)⁵ln α(s)) corrections to the heavy quarkonium spectrum. (C) 1999 Published by Elsevier Science B.V.
