A global fit to the anomalous magnetic moment, b -> Xs-gamma and Higgs limits in the constrained MSSM

De Boer, Willem; Huber, M.; Sander, C.; Kazakov, D.I.

New data on the anomalous magnetic moment of the muon together with the b -> Xsgamma decay rate are considered within the supergravity inspired constrained minimal supersymmetric model. We perform a global statistical X² analysis of these data and show that the allowed region of parameter space is bounded from below by the Higgs limit, which depends on the trilinear coupling and from above by the anomalous magnetic moment aµ. The newest b ->Xsgamma data deviate 1.7# from recent SM cal­culations and prefer a similar parameter region as the 2.6# deviation from aµ.
