Muon anomalous magnetic moment and the stabilized Randall-Sundrum scenario

We study the effects of extra dimension on the muon anomalous magnetic moment in the stabilized Randall-Sundrum scenario. The effects of the Kaluza-Klein states heavier than the cut-off scale expected to be of order $\Lambda_\pi$ are neglected. Contribution from the spin-2 Kaluza-Klein states dominates over that from the spin-0 radion. The recent BNL E821 results impose a strict constraint on the parameter space of the model: $\Lambda_\pi \approx 0.4 - 2.1$ TeV with $k/ M_{\rm Pl} =0.01 - 0.1$. Small $k/M_{\rm Pl}$ is preferred if $\Lambda_\pi$ is TeV scale.
