Constraints on supersymmetry from FCNC and CP violation

Abstract

We consider FCNC and CP violating processes mediated by gluino exchange in generalized supersymmetric theories. We present the constraints on flavour (F) changing squark mass terms at the electroweak energy scale, focusing our analysis on $\Delta F=2$ transitions. Results are also given for $\Delta F=1$ CP conserving processes both in the hadronic and leptonic sectors, while we limit ourselves to some remarks on the relevance of box diagrams in the evaluation of ${ϵ}^{\prime }/ϵ$.
