Effective messenger sector from dynamical supersymmetry breaking

In the framework of the dynamical supersymmetry breaking we construct the messenger sector as the effective theory of supersymmetry breaking sector, which is based on the SU(3) x SU(2) model of Affleck, Dine and Seiberg. In our model, messenger superfields with the non-renormalizable interaction are contained. By minimizing the scalar potential, we show that the supersymmetry breaking can be communicated to the visible sector without breaking QCD color. In this model there appear various scales. Supersymmetry breaking scale turns out to be the intermediate scale (similar to 10(10) GeV) between the GUT scale and the soft supersymmetry breaking scale. (C) 1997 Elsevier Science B.V.
