Abstract
We consider supersymmetric extensions of the standard model with general non-universal soft breaking terms. We analyse in a model-independent way the constraints on these terms at the electroweak energy scale coming from gluino mediated flavour ( F) changing neutral current and CP-violating processes. We have computed the complete ΔF = 1 and ΔF = 2 effective hamiltonian for gluino mediated processes, including for the first time the effect of box diagrams in the evaluation of ϵ′ ϵ . We present numerical results for the constraints on these non-universal soft breaking terms for different values of the parameters, extending the analysis also to the leptonic sector. A comparison with previous results in the literature is given.
