BRS Cohomology, Composite Operators and the Supersymmetric Standard   Model
  Supersymmetry might be broken, in the real world, by anomalies that affect composite operators, while leaving the action supersymmetric. New constraint equations that govern the composite operators and their anomalies are examined. It is shown that the supersymmetric standard model has special properties that allow simple and physically interesting solutions to the constraint equations.
