Implications of the recent measurement of Bs– mixing on SUSY models

We study the Bs– mixing and B→Xsγ within SUSY models with gluino-mediated flavor violation, and derive new bounds on the mass insertion parameters. The new bounds on the LL or RR insertion is now significant compared with the previous studies. The constraint becomes especially strong at large tan β due to the induced LR or RL insertion through the double mass insertion mechanism. The case LL=RR is also strongly constrained. These new constraints exclude some SUSY flavor models based on flavor symmetry groups. On the other hand, most SUSY models with universal scalar masses at high energy scale are safe from these bounds. We also discuss other observables and how to test the SM and SUSY models further in the future experiments.
