Yukawa textures and anomaly mediated supersymmetry breaking

We present a detailed analysis of how a mixed-anomaly-free U1 symmetry can be used to both resolve the slepton mass problem associated with Anomaly Mediated Supersymmetry Breaking and generate the fermion mass hierarchy via the Froggatt-Nielsen mechanism. Flavour changing neutral currents problems are evaded by a specific form of the Yukawa textures
