B0- anti B0 mixing, B→J/ψKS and B→Xdγ in general MSSM

We consider the gluino-mediated SUSY contributions to B0-B0 mixing, B→JψKs and B→Xdγ in the mass insertion approximation. We find the (LL) mixing parameter can be as large as vertical stroke (δ13d)LL vertical stroke <or∼2 x 10-1, but the (LR) mixing is strongly constrained by the B→Xdγ branching ratio and we find vertical stroke (δ13d)LR vertical stroke <or∼10-2. The implications for the direct CP asymmetry in B→Xdγ and the dilepton charge asymmetry (All) are also discussed, where substantial deviations from the standard model (SM) predictions are possible.
