【 摘 要 】

We derive sum rules for the sparticle masses in different models of supersymmetry breaking. This includes the gravity-mediated models (SUGRA models) as well as models in which supersymmetry breaking terms are induced by super-Weyl anomaly (AMSB models). These sum rules can help in distinguishing between these models. In particular, we obtain as upper bound on the mass of the lightest neutralino as a function of the gluino mass in SUGRA and AMSB models.
