Stringy World Branes and Exponential Hierarchies


We describe heterotic string and M-theory realizations of the Randall-Sundrum (RS) scenario with N = 2 and N = 1 supersymmetry in the bulk. Supersymmetry can be broken only on the world brane, a scenario that has been proposed to account for the smallness of the cosmological constant. An interesting prediction from string duality is the generation of a warp… (More)
