g-2 In the custodially protected RS model

Understand

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.
