Abstract
In the "central" region of moduli space of string theories, which is most l ikely to describe the "real world," the string coupling is about unity and the volume of compact dimensions is about the string volume. We map this re gion. assuming that the string coupling and compact volume moduli are chira l superfields of N = 1 supergravity in four dimensions, and requiring that the supersymmetry (SUSY) breaking scale is about the weak scale and that th e cosmological constant be acceptably small. We find that the SUSY breaking field has a weak scale mass and a flat potential, that the potential is st eep in other directions, and that there are additional nearby minima with a large negative cosmological constant.
