“…Therefore, it is not an easy task to get (δ d LR ) 23 of order 10 −2 . However, it was realized that with intermediate/large tan β, the double mass insertions could be quite relevant and may lead to an effective (δ d LR ) 23 of the required order even 3 with universal A-terms [14]. This can be seen from the explicit dependence of (δ d LR(RL) ) 23 on the LL(RR) mixing, which is give by…”

We analyze the possibility of probing the supersymmetric flavor structure through the constraints of the K and B meson systems and those of the electric dipole moments. We show that combining these constraints would favor SUSY models with large flavor mixing either in LR(RL) or LL but with a very small RR and intermediate/large tan β. Large LR mixing requires specific patterns for trilinear A-terms, while LL mixing seems quite natural and easier to obtain. We present an example for this class of models and show how it can accommodate the current CP asymmetries experimental results.

We review the theoretical status of b → s hadronic penguin decays in the Standard Model and beyond. We summarize the main theoretical tools to compute Branching Ratios and CP asymmetries for b → s penguin dominated nonleptonic decays, and discuss the theoretical uncertainties in the prediction of time-dependent CP asymmetries in this processes. We consider general aspects of b → s transitions beyond the Standard Model. Then we present detailed predictions in supersymmetric models with new sources of flavor and CP violation.

“…This is due to the fact that the main SUSY contribution is still through the C 8g which is enhanced by the chirality flipped factor mg/m b . In the literatures [16], this contribution has been considered in analyzing the CP asymmetry of B → φK and it was called as LL contribution, as indication for the large mixing in the squark mass matrix and dominant effect of (δ d LL ) 23 . However, we prefer to work with the notation LR eff to be able to trace the effective operators that may lead to dominant contributions for different B decay channels.…”

We analyze the supersymmetric contributions to the direct and mixing CP asymmetries and also to the branching ratios of the B → Kπ decays in a model independent way. We consider both gluino and chargino exchanges and emphasize that a large gluino contribution is essential for saturating the direct and mixing CP asymmetries. We also find that combined contributions from the penguin diagrams with chargino and gluino in the loop could lead to a possible solution for the branching ratios puzzle and account for the results of R c and R n within b → sγ constraints. When all relevant constraints are satisfied, our result indicates that supersymmetry favors lower values of R c . Finally we study the correlations between the mixing CP asymmetry S K 0 π 0 and mixing CP asymmetries of the processes B → φK and B → η ′ K. We show that it is quite possible for gluino exchanges to accommodate the results of that observables
