Notes:
Tools that have been developed for the extension of the Sterman–Weinberg formula in two-loop order are presented. They are the essential ingredients for any perturbative two-loop calculation in a massless theory. Introducing dimensional regularization, this paper deals with poles up to fourth order in the dimensional parameters. The virtual two-loop integrations as well as real ones over phase space are studied.
