Supersymmetric models with anomalous U(1) mediated supersymmetry breaking

We construct realistic supergravity models where supersymmetry breaking arises from the D terms of an anomalous U(1) gauge symmetry broken at the Planck scale. The effective action for these theories at sub-Planck energies (including higher dimensional terms in the superpotential) severely restricted by the U(1) symmetry and by the assump...更多
