Automating One-Loop Calculations with FeynArts, FormCalc, and LoopTools — •Thomas Hahn — Institut für Theoretische Physik, Universität Karlsruhe, 76128 Karlsruhe

Three programs are presented for automatically generating and calculating Feynman diagrams: the diagrams are generated with FeynArts, algebraically simplified with FormCalc, and finally evaluated numerically using the LoopTools package. The calculations are performed analytically as far as possible, with results given in a form well suited for numerical evaluation. The latter is then straightforward with the utility programs provided by FormCalc and the implementations of the one-loop integrals in LoopTools.
