Yukawa textures and anomaly mediated supersymmetry breaking Original Research Article

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.
