Query: Two Loop Computation of the Schroedinger Functional in Lattice QCD   We compute the Schroedinger functional (SF) for the case of lattice QCD with
Wilson fermions (with and without SW improvement) at two-loop order in lattice
perturbation theory. This allows us to extract the three-loop beta-function in
the SF-scheme. These results are required to compute the running coupling, the
Lambda-parameter and quark masses by finite size techniques with negligible
systematic errors. In addition our results enable the implementation of
two-loop O(a) improvement in SF-simulations.
