Abstract

In the Randall-Sundrum model, a bulk neutrino field in the 5-dimensional space-time can give rise to tiny Dirac masses to neutrinos. In such a scenario, we have computed the contribution of the bulk neutrino field to the anomalous magnetic moment (g2)μ(g-2)_\mu of muon. We have computed this contribution in the 't Hooft-Feynman gauge and have found that the contribution has the right sign to fit the current discrepancy between the experiment and the standard model value of (g2)μ(g-2)_\mu. We have also studied possible constraints on the model parameters by including contributions to (g2)μ(g-2)_\mu from other sources such as bulk gravitons.
