Abstract

Quantum chromo dynamics (QCD) is supposed to be the fundamental theory of strong interactions. Unfortunately, QCD can be perturbatively solved only in the region of asymptotic freedom, i.e. for high momenta1. For small momenta, the expansion parameter of perturbation theory, the strong coupling constant αs, is of the order of unity, and one is forced to use non—perturbative methods. One of the most successful non—perturbative approaches are lattice gauge calculations2. These calculations are especially suitable to study perturbative as well as non—perturbative effects in QCD. The presently available lattice data mostly concern the simulation of SU(N) pure gauge theory3. Therefore, we also restrict ourselves to gluons in our present considerations. Moreover, only in the pure gauge case one believes to have lattice artefacts well under control4. Thus, only in this case we are able to draw conclusions for the continuum theory from the lattice data.
