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 &Dgr; a &mgr; g ≈ 2.72 × 10 − 10 1 TeV T 2 ?>basically independent of the model parameters except for the Kaluza–Klein 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.
