Stability issues in Kalb-Ramond/dilaton braneworld scenarios

I summarize the Randall-Sundrum braneworld scenario, and its application to solving the hierarchy problem in the Standard Model of elementary particles. A generalized Randall-Sundrum scenario is presented, which includes the presence of string-inspired massless Kalb-Ramond and dilaton fields, and includes their backreaction on the metric. It is shown that in such a scenario, solutions exist which can achieve the desired warping on the Standard Model brane, and which stabilize the modulus corresponding to the radius of the extra dimension.
