摘要：
In this paper we discuss supersymmetric contributions to the direct CP asymmetries of B -> pi K* and B -> rho K decays. We use Soft Collinear Effective Theory as a framework for our study. We show that within the standard model and including the next leading order QCD corrections, the predicted CP asymmetries can not accommodate the experimental measurements. We show that non-minimal flavor SUSY contributions mediated by gluino exchange can enhance the CP asymmetries significantly to accommodate the experimental measurements.
