Title: THE COSMOLOGICAL CONSTANT PROBLEM: A STRING THEORY APPROACH
Abstract: We propose that stringy symmetries play a crucial role in the resolution of the cosmological constant problem. In the presence of constant fluxes along compact directions, it is possible to construct potentials for the moduli. For suitable choice of fluxes, they admit minima with non-zero cosmological constant and such solutions break duality symmetry. The corresponding duality symmetric solutions have vanishing cosmological constant. The naturalness hypothesis of 't Hooft may be invoked to argue that the cosmological constant must remain small since symmetry preserving solutions correspond to vanishing cosmological constant.
