Locally localized gravity
Abstract
We study the fluctuation spectrum of linearized gravity around nonfinetuned branes. We focus on the case of an AdS_{4} brane in AdS_{5}. In this case, for small cosmological constant, the warp factor near the brane is essentially that of a Minkowski brane. However, far from the brane, the metric differs substantially. The space includes the AdS_{5} boundary, so it has infinite volume. Nonetheless, for sufficiently small AdS_{4} cosmological constant, there is a bound state graviton in the theory, and fourdimensional gravity is reproduced. However, it is a massive bound state that plays the role of the fourdimensional graviton.
