Abstract We describe the implementation of the MSSM in the diagram generator FeynArts and the calculational tool FormCalc . This extension allows to perform loop calculations of MSSM processes almost fully automatically. The actual implementation has two aspects: The MSSM Feynman rules are specified in a new model file for FeynArts . The computation of the parameters in the MSSM Lagrangian from the input parameters is realized as a Fortran subroutine in the framework of FormCalc . The model file does not depend on the latter, however, and can be used even if one does not want to continue the calculation with FormCalc . The Feynman rules have been entered in a very generic way to allow, e.g., scenarios with complex parameters, and have been tested extensively by reproducing known results for several non-trivial scattering processes.
