Abstract

摘要

We present a braneworld model within the framework of string theory in which the four-dimensional spacetime is associated with a wrapped 5-brane. Although the transverse space includes a non-compact hyperbolic 3-space, gravity is nonetheless localised on the brane, with a mass gap separating the massless graviton from a continuum of massive spin-2 states. The model evades some previous “no-go theorems”for braneworld models in string theory.
