QCD Box Graphs and the Quark-Antiquark Potential
arXiv:hep-ph/9602276 · doi:10.1007/BF02909197
Abstract
The 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'' $O(\a^4)$ corrections in the non-Abelian case differ from the well known corrections of the same order in QED.
