SPARTICLE SPECTRUM CONSTRAINTS

The supersymmetric standard model with supergravity-inspired soft brea king terms predicts a rich spectrum of sparticles to be discovered at the SSC, LHC, and NLC. Because there are more supersymmetric particles than unknown parameters, one can write down sum rules relating their masses. We discuss the spectrum of sparticles from this point of view. Some of the sum rules do not depend on the input parameters and can b e used to test the consistency of the model, while others are useful i n determining the input parameters of the theory. If supersymmetry is discovered but the sum rules turn out to be violated, it will be evide nce of new physics beyond the minimal supersymmetric standard model wi th universal soft supersymmetry-breaking terms.
