RandallSundrum Brane Model with 7D Antide Sitter Space
Abstract
In the same sense that 5D antide Sitter space (AdS{sub 5}) warped geometries arise naturally from type IIB string theory with stacks of D3 branes, AdS{sub 7} warped geometries arise naturally from M theory with stacks of M5 branes. We compactify two spatial dimensions of AdS{sub 7} to get AdS{sub 5}x{sigma}{sup 2}, where the metric for {sigma}{sup 2} inherits the same warp factor as appears in the AdS{sub 5}. We analyze the 5D spectrum in detail for the case of a bulk scalar or a graviton in AdS{sub 5}xT{sup 2}, in a setup which mimics the first RandallSundrum model. The results display novel features which might be observed in experiments at the CERN Large Hadron Collider. For example, we obtain TeV scale string winding states without lowering the string scale. This is due to the double warping which is a generic feature of winding states along compactified AdS directions. Experimental verification of these signatures of AdS{sub 7} could be interpreted as direct evidence for M theory.

We compactify two spatial dimensions of AdS{sub 7} to get AdS{sub 5} x {Sigma}{sup 2}, where {Sigma}{sup 2} is e.g. a torus T{sup 2} or a sphere S{sup 2}. The metric for {Sigma} inherits the same warp factor as appears in the AdS{sub 5}. Bulk fields generically have both KaluzaKlein and winding modes associated with {Sigma}.

7D RandallSundrum cosmology, branebulk energy exchange, and holography
We discuss the cosmological implications and the holographic dual theory of the 7D RandallSundrum gravitational setup. Adding generic matter in the bulk on the 7D gravity side, we study the cosmological evolution inferred by the nonvanishing value of the branebulk energy exchange parameter. This analysis is achieved in detail for specific assumptions on the internal space evolution, including analytical considerations and numerical results. The dual theory is then constructed, making use of the holographic renormalization procedure. The resulting renormalized 6D conformal field theory is anomalous and coupled to 6D gravity plus higher order corrections. The critical point analysis on themore » 
RandallSundrum two Dbrane model
In the RandallSundrum two Dbrane system, we derive the gravitational theory on the branes. It is turned out from the consistency that one Dbrane has the negative tension brane under RandallSundrum tuning and both gauge fields on the brane are related by scale transformation through the bulk R(Ramond)R/NS(NeveuSchwarz)NS fields. As with the single Dbrane case, the gauge field which is supposed to be localized on the brane does not couple to the gravity on the branes. 
Gravity in the RandallSundrum two Dbrane model
We analyze the RandallSundrum two Dbrane model by linear perturbation and then consider the linearized gravity on the D brane. The qualitative contribution from the KaluzaKlein modes of gauge fields to the coupling to the gravity on the brane will be addressed. As a consequence, the gauge fields localized on the brane are shown not to contribute to the gravity on the brane at large distances. Although the coupling between gauge fields and gravity appears in the next order, the ordinary coupling cannot be realized. 
Radius stabilization and brane running in the RandallSundrum type 1 model
We study the effective potential of a scalar field based on the 5D gauged supergravity for the RandallSundrum type one brane model in terms of the brane running method. The scalar couples to the brane such that the BogomolnyiPrasadSommerfield conditions are satisfied for the bulk configuration. The resulting effective potential implies that the interbrane distance is undetermined in this case, and we need a small BogomolnyiPrasadSommerfield breaking term on the brane to stabilize the interbrane distance at a finite length. We also discuss the relationship to the GoldbergerWise model.
