Abstract

It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale Msusy through the formula ΛMp4(Msusy/Mp)8. We point out that a similar relation naturally arises in the codimension two solutions of warped spacetime varying compactifications of string theory, in which nonisotropic stringy moduli induce a small but positive cosmological constant.
