Anomalous magnetic moment of the muon in the Randall-Sundrum model with custodial protection — Martin Beneke¹, •Paul Moch¹, and Jürgen Rohrwild^1,2 — 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

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 m_kk≈2.5T.
