From superpotential to model files for FeynArts and CalcHep/CompHep Original Research Article

SARAH is a Mathematica package for building and studying supersymmetric models. It calculates for a given superpotential and gauge sector the full Lagrangian of a model. With the new version of SARAH it is possible to calculate automatically all interactions for the different eigenstates and write model files for FeynArts and CompHep/CalcHep. In addition, the tadpole equations are calculated, gauge fixing terms can be given and ghost interactions are added, particles can be integrated out and non-supersymmetric limits of the theory can be chosen. CP and flavor violation can easily be switched on or off.
