Scalar Bosons Evolving in an Asymptotically A d S 5 Bulk with A d S−Branes Everywhere

In a brane scenario, we are investigating the behavior of scalar bosons evolving in an asymptotically A d S 5 bulk, with k = −1−RW branes, assuming that the scalar field supporting the geometry is depending on the fifth coordinate alone. For the derived scale function and warp factor, we write down the full expression of the orthonormal modes characterizing the scalar test particle, pointing out the allowed KK-mass spectrum and a non-trivial quantization law for the bulk mass parameter.
