Localized Massive Gravity from B Fields
Abstract
Description
We consider five-dimensional domain-wall solutions which arise from a sphere reduction in M-theory or string theory and have the higher-dimensional interpretation as the near-horizon region of p-branes in constant, background B fields. We analyze the fluctuation spectrum of linearized gravity and find that there is a massive state which is localized and plays the role of the four-dimensional graviton.
