g-2 In the custodially protected RS model

Abstract

We study leptonic operators of dimension six in the custodially protected Randall-Sundrum model. Their contribution to the anomalous magnetic moment of the muon is evaluated. We find that the contribution to g-2 due to diagrams with an internal gauge boson exchange is given by approximately 2.72*10^-10 (1 TeV/T)^2 basically independent of the model parameters except for the KK mass scale T---a factor of more than 3 larger than in a scenario without custodial protection. We also investigate the impact of contributions to the dipole operators due to an internal Higgs exchange, which can provide sizable albeit model-dependent corrections.
