Abstract
We show that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry. We briefly discuss the role of such small constants in moduli stabilization and understanding the huge hierarchy between the Planck and electroweak scales.

We focus on orbifold compactifications [12] since they possess many discrete symmetries, which, as it turns out, imply approximate Uð1ÞR symmetries of the superpotentials describing the effective field theories derived from these constructions
