  "abstract": "Recent results from CDF and D{\\O} collaborations favor a large CP asymmetry in B_s^0-\\bar{B}_s^0 mixing, while the standard model prediction is very small. Such a large phase may imply sizable new physics effects in B_s^0-\\bar{B}_s^0 mixing. We compute the gluino-mediated supersymmetry contributions to B_s^0-\\bar{B}_s^0 mixing, B_s->K^{(*)-}K^{(*)+} and B->X_s\\gamma decays in the frame of the mass insertion approximation. Combining the constraints of \\DeltaM_s, \\Delta\\Gamma_s, \\phi^{J/\\psi\\phi}_s, B(B_s->K^{-}K^{+}) and B(B->X_s \\gamma), we find that the effects of the constrained LL and RR insertions in B_s->K^{(*)-}K^{(*)+} decays are small because of the absence of gluino mass enhancement. For m^2_{\\tilde{g}}/m^2_{\\tilde{q}}=9, the constrained LR insertion can provide sizable contributions to all observables of B_s->K^{(*)-}K^{(*)+} decays except A^{dir}_{CP}(B_s->K^{-}K^{+}), and many observables are sensitive to the modulus and the phase of the LR insertion parameter. Near future experiments at Fermilab Tevatron and CERN LHC-b can test these predictions and shrink/reveal the mass insertion parameter spaces.",
