Abstract

We study the effects of the Kaluza-Klein gravitons in the Randall-Sundrum model on the recent BNL measurements of the muon (g - 2) deviation from the standard model prediction. By examining the J-partial wave unitarity bounds of the elastic process γγ → γγ, the cut-off on the number of massive KK gravitons, n_c, has been introduced. We found that the recently measured Δa_μ can be accommodated in the RS model, within the natural parameter space allowed by the perturbative unitarity. For example, dozens (hundreds) of the n_c for Λπ = 1 ∼ 2 TeV (3 TeV) can explain the reported Δa_μ.
