Abstract
We investigate supersymmetric models in which an anomalous U(1)(x) symmetry explains the Yukawa hierarchy, and the related D-x-term plays a role in su persymmetry breaking. We use a bottom-up approach to model building. Phenom enological viability leads to a scenario with degenerate squark and slepton spectra and with heavy gauginos. Features of a Kahler potential that allow s for such a scenario are described. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
