                                    Resum

  Recent results from B->J/psi K_s CP asymmetries are still somewhat lower
 than the SM expectations. In this talk, we present the predictions for this
 asymmetry in two minimal extensions of the SM. In the first part, a generic
 MSSM with arbitrary soft breaking terms at the GUT scale is analyzed and we
     find that moderate deviations from the SM predictions are naturally
 accommodated. Finally an extension of the SM with the addition of a vector
 like down quark is presented as a typical model where large deviations from
                     the SM expectations are possible.
