Flavor structure of soft SUSY breaking parameters

Flavor structure of soft supersymmetry breaking parameters is studied in a certain type of effective supergravity theory derived from the moduli/dilaton dominated supersymmetry breaking. Some interesting sum rules for the soft scalar masses are presented. They constrain their flavor structure and predict some interesting patterns appeared 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.
