Abstract

After the shutdown of the large electron-positron collider atCERN, the search for CP violation and flavour changing neutralcurrent (FCNC) phenomena acquired a privileged role in our questfor new physics beyond the electroweak standard model (SM). Most extensions of the SM exhibit new sources of CP violationand FCNC. In particular, the minimal supersymmetric extension ofthe SM presents several new phases and flavour structures inaddition to those already present in the SM. Therefore,supersymmetry may have a good chance to manifest some departurefrom the SM in this particularly challenging class of rarephenomena. On the other hand, it is also apparent that CPviolation and FCNC generally represents a major constraint onany attempt at model building beyond the SM. In this work, wereview the status of FCNC and CP violation in supersymmetricextensions of the SM and discuss the possibilities of theseindirect searches in the quest for supersymmetry.
