Abstract

We present a combined study of the muon anomalous magnetic moment, a_μ ≡ (g-2)_μ /2, and b → s γ decay in the minimal supersymmetric standard model with gauge-mediated supersymmetry-breaking. Combining new experimental data on a_μ and the branching ratio for b → s γ, useful limits on the parameter space of these models are derived. Bounds on supersymmetric particle masses as a function of tan β are also presented.
