Sumario: | The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g-2 is promising to probe a theory involving supersymmetry. We have studied the constraints on minimal Anomaly Mediated Supersymmetry Breaking (AMSB) model using the current data of muon g-2 from Brookhaven. A scenario of seeing no deviation from the Standard Model is also considered, within $2\sigma$ limit of the combined error from the Standard Model result and the Brookhaven predicted uncertainty level. The resulting constraint is found to be complementary to what one obtains from $b \to s+ \gamma$ bounds within the AMSB scenario, since only a definite sign of $\mu$ is effectively probed via $b \to s+ \gamma$. A few relevant generic features of the model are also described for disallowed regions of the parameter space. |
