QCD Box Graphs and the Quark-Antiquark Potential

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

The ttˉt\bar{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(\a4)O(\a^4) corrections in the non-Abelian case differ from the well known corrections of the same order in QED.
