Gravitational excitons - fluctuating particles from extra dimensions

Günther, U.; Zhuk, A.

Abstract

We show that for warped product space-times the conformal (geometric moduli) excitations of the internal compactified factor spaces should be observable as massive scalar fields in the external space-time. These scalar fields (gravitational excitons) describe weakly interacting particles and can be considered as dark matter component. On the other hand, they provide possible values for the effective cosmological constant.
