g-2 of the muon in SUSY Models with Gauge Multiplets in the Bulk of Extra-Dimensions

Abstract

We analyze the supersymmetric contributions to the anomalous magnetic moment of the muon (a_μ) in the framework of pure and gaugino-assisted anomaly mediation models, and gaugino mediation models. In the last two models the gauge multiplets propagate in the higher dimensional bulk, providing a natural mechanism for solving the problem of negative squared slepton masses present in the pure anomaly mediation models. In the light of the new BNL results for a_μ, we found that the pure and gaugino-assisted anomaly mediation models are almost excluded by the BNL constraints at 2σlevel when combined with CLEO constraints on b->sg at 90 % of C.L. In contrast, the gaugino mediation models provide extensive regions in the SUSY parameter space where both of these constraints are satisfied.
