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(mαs5) in the heavy quarkonium spectrum. These leading logs, when ΛQCD≪mαs2, give the complete O(mαs5lnαs) corrections to the heavy quarkonium spectrum.
