The heavy quarkonium spectrum at order $m\alpha_{s}^{5}\ln\alpha_{s}$

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 $\Lambda_{QCD} \ll m\alpha_s^2$, give the complete $O(m\alp...
