Multiloop vacuum bubbles for hot QCD — •Ervin Bejdakic — Faculty of Physics, Bielefeld, Germany

We present some methods used to compute vacuum bubbles needed for the perturbative computation of the pressure of hot QCD.First we introduce the difficulties of doing perturbative calculations in hot QCD, present a general strategy for separating the scales of hot QCD in effective theories and show how to compute analyticaly (some) four-loops scalar "master"-integrals of that effective theory.
