Supersymmetric contribution to the CP asymmetry of B-> J/\psi \phi in the light of recent B_s -\bar{B}_s measurements

We derive new model independent constraints on the supersymmetric extensions of the standard model from the new experimental measurements of B_s -\bar{B}s mass difference. We point out that supersymmetry can still give a significant contribution to the CP asymmetry of B_s ->J/\psi \phi that 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-> \phi K and B - >\eta’ 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 \Delta M{B_s} results and also induces significant CP asymmetries in B_s ->J/\psi \phi, B->\phi K and B ->\eta’ K processes.
