| Abstract: | The $tbar t$ system allows a truly perturbative treatment of the potential. Completing previous computations, we calculate the contributions of QCD box graph corrections, which make the “relativistic”O(α 4) corrections in the non-Abelian case differ from the well known corrections of the same order in QED. |
