摘要
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 I-Eggs mass and b --> sgamma put severe constraints on the model and large tan beta is favored to enhance the Muon g - 2. (C) 2003 Elsevier Science B.V. All rights reserved.
