Flavor structure of soft SUSY-breaking parameters

Abstract

Flavor structure of soft supersymmetry-breaking parameters is studied in a certain type of effective supergravity theory derived from moduli- or dilaton-dominated supersymmetry breaking. Some interesting sum rules for soft scalar masses are presented. They constrain their flavor structure and predict some interesting patterns appearing in soft scalar masses in the nonuniversal case. We also study the alignment phenomena in the flavor space of soft breaking parameters due to Yukawa couplings and discuss their phenomenological consequences. © 1996 The American Physical Society.
