A complete analysis of FCNC and CP constraints in general SUSY extensions of the standard model
Abstract
We analyze the full set of constraints on gluino- and photino-mediated SUSY contributions to FCNC and CP violating phenomena. We use the mass insertion method, hence providing a model-independent parameterization which can be readily applied in testing extensions of the MSSM. In addition to clarifying controversial points in the literature, we provide a more exhaustive analysis of the CP constraints, in particular concerning ɛ'/ ɛ. As physically meaningful applications of our analysis, we study the implications in SUSY-GUT's and effective supergravities with flavour nonuniversality. This allows us to detail the domain of applicability and the correct procedure of implementation of the FC mass insertion approach.
