摘要：
In quantum chromodynamics (QCD), the binding energy of an infinitely heavy quark-antiquark pair in a color singlet state can be calculated as a function of the distance. We investigate this static potential of QCD perturbatively and calculate the hill two-loop coefficient, correcting an earlier result. Beyond this order, the perturbative expansion breaks down.
