Abstract

We point out a generic problem in string-inspired supergravity models with an anomalous U(1)XU(1)_X. A large number of matter multiplets charged under U(1)XU(1)_X remain massless above the supersymmetry-breaking scale because of degeneracy of vacua solving the D-flatness conditions. A toy model is analyzed as an illustration of the mechanism; we find the surprising result that many scalars remain massless after supersymmetry-breaking in a hidden sector.
