Anomalous magnetic moment of the muon in the Randall-Sundrum model with custodial protection — Martin Beneke1, •Paul Moch1, and Jürgen Rohrwild1,2 — 1Physik Department T31, Technische Universität München — 2Rudolf Peierls Centre for Theoretical Physics, University of Oxford
We compute the anomalous magnetic moment of the muon in the Randall-Sundrum model with custodial protection using a brane-localized Higgs. We apply a fully five dimensional (5D) framework to calculate the matching coefficients of the effective field theory at the electroweak scale. The extra contribution to the muon anomalous magnetic moment derived from the model-independent gauge-boson exchange contribution is
| Δ aµ=2.94·10−10× | ⎛ ⎝ | T/1TeV | ⎞ ⎠ | 2 |
where 1/T denotes the location of the Tev brane in conformal coordinates. The parameter T is connected to the mass of the lowest KK excitation of a standard model gauge boson by mkk≈2.5T.
