We perform an extensive study of FCNC and
CP Violation
within Supersymmetric (SUSY) theories with particular emphasis put on processes governed by b→s transitions and of their correlations with processes governed by b→d transitions, s→d transitions, D0–D¯0 oscillations, lepton flavour violating decays, electric dipole moments and (g−2)μ. We first perform a comprehensive modelindependent analysis of ΔF=2 observables and we emphasize the usefulness of the Rb–γ plane in exhibiting transparently various tensions in the present UT analyses. Secondly, we consider a number of SUSY models: the general MSSM, a flavourblind MSSM, the MSSM with
Minimal Flavour Violation
as well as SUSY flavour models based on Abelian and nonAbelian flavour symmetries that show representative flavour structures in the soft SUSY breaking terms. We show how the characteristic patterns of correlations among the considered flavour observables allow to distinguish between these different SUSY scenarios. Of particular importance are the correlations between the CP asymmetry Sψϕ and Bs→μ+μ−, between the anomalies in SϕKS and Sψϕ, between SϕKS and de, between Sψϕ and (g−2)μ and also those involving lepton flavour violating decays. In our analysis, the presence of righthanded currents and of the double Higgs penguin contributions to Bs mixing plays a very important role. We propose a “DNAFlavour Test” of NP models including Supersymmetry, the
Littlest Higgs
model with Tparity and the Randall–Sundrum model with custodial protection, with the aim of showing a tool to distinguish between these NP scenarios, once additional data on flavourchanging processes become available. As a byproduct, we present the SM prediction for BR(B+→τ+ν)=(0.80±0.12)×10−4 that follows solely from an analytical formula for this branching ratio in terms of ΔMs,d and SψKS asymmetry and which does not involve Vub and FB uncertainties.
