【 摘 要 】

For more than a decade the SM determination of the anomalous magnetic moment of the muon, (g - 2)μ, has shown a deviation from its experimental value. There is currently a more than 3 standard deviations difference. However, the SM determination could be greatly improved, mainly by the reduction of the uncertainties associated to the calculation of the hadronic contributions to (g - 2)μ. Supersymmetric models are capable to explain the difference between experimental and SM values of (g - 2)μ. In these models, the study of the correlations to other observables, for example BR(μ → eγ), can help to select models where constraints from the LHC are compatible and can give definite predictions.
