“…This type of models seems natural and can be obtained by a minimal relaxation for the universality assumption of the minimal supersymmetric standard model (MSSM). Moreover, large tan β is also favored by other experimental results like the branching ratio of B → µ + µ − [3].…”

We analyze the possibility of probing the supersymmetric flavor structure through the constraints of the K and B meson systems and those of the electric dipole moments. We show that combining these constraints would favor SUSY models with large flavor mixing either in LR(RL) or LL but with a very small RR and intermediate/large tan β. Large LR mixing requires specific patterns for trilinear A-terms, while LL mixing seems quite natural and easier to obtain. We present an example for this class of models and show how it can accommodate the current CP asymmetries experimental results.

“…Thus the decay width can grow with tan 6 β and the BR can be much larger than in the SM [43], see Ref. [44] for a recent review. The available corrections in the MSSM consist of the full one-loop evalution and the leading two-loop QCD corrections.…”

Electroweak precision observables in the minimal supersymmetric standard model

The current status of electroweak precision observables in the Minimal Supersymmetric Standard Model (MSSM) is reviewed. We focus in particular on the W boson mass, M W , the effective leptonic weak mixing angle, sin 2 θ eff , the anomalous magnetic moment of the muon, (g − 2) µ , and the lightest CP-even MSSM Higgs boson mass, m h . We summarize the current experimental situation and the status of the theoretical evaluations. An estimate of the current theoretical uncertainties from unknown higher-order corrections and from the experimental errors of the input parameters is given. We discuss future prospects for both the experimental accuracies and the precision of the theoretical predictions. Confronting the precision data with the theory predictions within the unconstrained MSSM and within specific SUSY-breaking scenarios, we analyse how well the data are described by the theory. The mSUGRA scenario with cosmological constraints yields a very good fit to the data, showing a clear preference for a relatively light mass scale of the SUSY particles. The constraints on the parameter space from the precision data is discussed, and it is shown that the prospective accuracy at the next generation of colliders will enhance the sensitivity of the precision tests very significantly. * email: Sven.Heinemeyer@cern.ch †

“…As long as minimal flavour violation is assumed, this implies for example that destructive interference between the H ± and χ ± contributions to b → sγ, and thus the specific sign µA t < 0 is favoured (see [102,103] for reviews and references and [104] for a recent thorough analysis of b-physics and SUSY). The interplay between rare b-decays and a µ is particularly strong in the framework of specific models such as minimal supergravity or gauge-mediated SUSY breaking.…”

Abstract.The present review is devoted to the muon magnetic moment and its role in supersymmetry phenomenology. Analytical results for the leading supersymmetric one-and two-loop contributions are provided, numerical examples are given and the dominant tan β sign(µ)/M 2 SUSY behaviour is qualitatively explained. The consequences of the Brookhaven measurement are discussed. The 2σ deviation from the Standard Model prediction implies preferred ranges for supersymmetry parameters, in particular upper and lower mass bounds. Correlations with other observables from collider physics and cosmology are reviewed. We give, wherever possible, an intuitive understanding of each result before providing a detailed discussion.
