Recent Muon g-2 Result in Deflected Anomaly-Mediated Supersymmetry Breaking
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 γ put severe constraints on the model and large β is favored to enhance the muon g-2.
