Static potential for heavy quarks and gluinos — •Tim Collet and Matthias Steinhauser — Institut für Theoretische Teilchenphysik, Karlsruher Institut für Technologie

The static potential is a fundamental parameter of QCD. For the case of heavy-quark bound states in the colour singlet and octet configuration it is known to three and two loop order, respectively. In this talk the potential for colour octet bound states, like gluinonium in supersymmetric theories, is discussed and results for the various colour configurations are presented in two-loop approximation.
