Title: Randall-Sundrum Brane Model with 7D Anti-de Sitter Space

Abstract

In the same sense that 5D anti-de 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 Randall-Sundrum 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.
