In the model, we introduce an approximate U(1) symmetry under which the supersymmetry breaking field is charged, although it is broken by a mass term of messenger fields to generate gaugino masses of order the weak scale. In a low-scale inflation model, we find regions in which the gravitino overproduction problem is avoided.24 pages, 3 figuresHigh Energy Physics - PhenomenologyAstrophysicsHigh Energy Physics - Theorytext
