QCD Box Graphs and the Quark-Antiquark Potential
W. Kummer, W. Moedritsch, A. Vairo
Abstract
The tt 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(4) corrections in the non-Abelian case differ from the well known corrections of the same order in QED.
