Neutrinos in Extra Dimensions and the Anomalous Magnetic Moments of Leptons
Abstract
The use of extra dimensional scenarios as models for neutrino mass affects many low energy observables. We consider the implications of virtual bulk neutrinos in precision experiments of the anomalous magnetic moments of the muon and the electron. We consider neutrino models in factorizable geometry of the type M4 x T as well as the sliced AdS5 non-factorizable geometry. In both geometries we find finite contributions to g-2 after summing over the KK excitations of the bulk neutrinos. In the case of Randall-Sundrum geometry, we find that the muon experiment is approaching the precision necessary to probe these models.
