Supersymmetry of Scattering Amplitudes and Green Functions in   Perturbation Theory
  We investigate the algebraic structure of supersymmetric Ward- and Slavnov-Taylor identities (STI) in field theories with global supersymmetry. We develop diagrammatical methods for STI in supersymmetric gauge theories within a generalized BRST formalism. These identities are used as consistency checks for the implementation of phenomenological supersymmetric models of elementary particle physics in Monte Carlo simulations. We discuss the infrastructure necessary for generalizing the matrix element generator O'Mega to supersymmetric field theories.
