Abstract

We derive new model independent constraints on the supersymmetric extensions of the standard model from the new experimental measurements of Bs -Bs mass difference. We point out that supersymmetry can still give a significant contribution to the CP asymmetry of Bs ->J/ψϕthat can be measured at the LHCb experiment. These new constraints on the LL and RR squark mixing severely restricted their possible contributions to the CP asymmetries of B-> ϕK and B - >η' K. Therefore, SUSY models with dominant LR flavor mixing is the only way to accommodate the apparent deviation of CP asymmetries from those expected in the standard model. Finally we present an example of SUSY non-minimal flavor model that can accommodate the new ΔMBs results and also induces significant CP asymmetries in Bs ->J/ψϕ, B->ϕK and B ->η' K processes.
