Phenomenological Constraints on Supersymmetric Models with an Anomalous U(1) Flavor Symmetry
Galit Eyal
Abstract
We investigate supersymmetric models in which an anomalous U(1)X symmetry explains the Yukawa hierarchy, and the related DX-term plays a role in supersymmetry breaking. We use a bottom-up approach to model building. Phenomenological viability leads to a scenario with degenerate squark and slepton spectra and with heavy gauginos. Features of a Kähler potential that allows for such a scenario are described.
