摘要：

We construct a supersymmetric vacuum of string theory in which the magnitude of the vacuum energy is < 10(-123) in Planck units. The mechanism that we introduce generates a well-controlled exponential hierarchy from an appropriate choice of the quantized parameters in the superpotential. Our approach provides a new angle on the cosmological constant problem.
