结果表明，在N_f=0处的Borel微扰静电势收敛良好，并且在1/r > 660 MeV处与猝灭晶格计算的结果非常一致。这表明Borel重定能很好地处理了重正子在静势中（以及在极质量中）的情况，并允许在重夸克物理的微扰计算中使用极质量。
We show that the Borel resummed perturbative static potential at N_f=0 converges well, and is in a remarkable agreement with the quenched lattice calculation at distances 1/r > 660 MeV. This shows that Borel resummation is very good at handling the renormalon in the static potential (and in the pole mass), and allows one to use the pole mass in perturbative calculation of heavy quark physics.
