Abstract

We study the deflected anomaly-mediated supersymmetry breaking (AMSB) scenario in the light of the recent result of the muon g-2 from Brookhaven E821 experiment. The E821 result suggests the deviation from the SM prediction, though there remain unsettled uncertainties. We find that the supersymmetric contribution to the muon g-2 can be O(10^-9), large enough to fill the deviation, with other experimental constraints satisfied. In particular, the Higgs mass and b → s γput severe constraints on the model and large tanβis favored to enhance the muon g-2.
