We perform all 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, D-0-(D) over bar (0)) oscillations, lepton flavour violating decays, electric dipole moments and (g - 2)(mu), We first perform a comprehensive model-independent analysis of Delta F = 2 observables and we emphasize the usefulness of the R-b-gamma plane in exhibiting transparently various tensions ill the present UT analyses. Secondly, we consider a number of SUSY models: the general MSSM, a flavour-blind MSSM, the MSSM with Minimal Flavour Violation as well as SUSY flavour models based oil Abelian and non-Abelian flavour symmetries that show representative flavour structures ill 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 S-psi phi and B-s -> mu(+)mu(-), between the anomalies lies S-phi KS and S-psi phi, between S-phi KS and d(e), between S-psi phi and (g - 2)(mu) and also those involving lepton flavour violating decays. In our analysis, the presence of right-handed Currents and of the double Higgs Penguin Contributions to B., mixing plays a very important role. We propose a DNA-Flavour Test of NP models including Supersymmetry, the Littlest Higgs model with T-parity and the Randall-Sundrum model with Custodial protection. with the aim of showing a tool to distinguish between these NP scenarios, once additional data oil flavour-changing processes become available. As a byproduct, we present the SM prediction for BR(B+ -> tau(+)v) = (0.80 +/- 0.12) x 10(-4) that follows solely from an analytical formula for this branching ratio in terms of Delta M-s,M-d and S-psi KS asymmetry and which does not involve V-ub and F-B Uncertainties.
