We study the effects of extra dimension on the muon anomalous magnetic moment in the stabilized Randall-Sundrum scenario. The effects of tile 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) approximate to 0.4-2.1 TeV with k/M-P1 = 0.01-0.1. Small k/M-P1 is preferred if Lambda (pi) is TeV scale. (C) 2001 Published by Elsevier Science B.V. References: 42
