Abstract
We derive an algorithm for automatic calculation of perturbative p-fun ctions and anomalous dimensions in any local quantum field theory with canonical kinetic terms. The infrared rearrangement is performed by i ntroducing a common mass parameter in all the propagator denominators. We provide a set of explicit formulae for all the necessary scalar in tegrals up to three loops. (C) 1998 Published by Elsevier Science B.V.
