SUSYCAL - SYMBOLIC COMPUTATIONS IN SUPERSYMMETRIC THEORIES

The calculation of supergraphs within the superfield-formalism entails complex expressions and numerous divergent integrals. This is even more so for non-covariant supergauges. SUSYCAL is a package of PASCAL procedures which is able to manipulate formulae and perform these calculations. The algebra of the non-covariant operators of the FD-gauge and the covariant derivatives is included in SUSYCAL as a fixed set of rules. This first version of SUSYCAL to be presented comprises also the (symbolic) evaluation of several divergent non-covariant self-energies. The method of dimensional regularization is used for all computations by SUSYCAL. Because of the universal applicability of the non-covariant operators, SUSYCAL is a tool for calculations in all N = 1 supersymmetric theories. © 1990.
