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 Λπ 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: Λπ≈0.4–2.1 TeV with k/MPl=0.01–0.1. Small k/MPl is preferred if Λπ is TeV scale.
