arXiv:hep-ph/0211288 · doi:10.1016/S0920-5632(03)80208-6
Abstract
We give technical details about the computational strategy employed in a recently completed investigation of the four-loop QCD free energy. In particular, the reduction step from generic vacuum bubbles to master integrals is described from a practical viewpoint, for fully massive as well as QED-type integrals.
