Gravitational excitons from extra dimensions

Gravitational excitons from extra dimensions

Günther, U.; Zhuk, A.

We study inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold under dimensional reduction and show that small inhomogeneous excitations of the scale factors of the internal spaces near minima of effective potentials should be observable as massive scalar particles (gravitational excitons) in the external space-time.

Keywords: string theory; moduli stabilization; scalar-tensor theory; higher dimensional gravity; dimensional reduction
