摘要：

We propose a simple gauge-mediated supersymmetry breaking model in which suitable soft breaking masses are dynamically generated without relying on the messenger gauge interaction. This model is constructed as an extention of the 3-2 model and needs no fine-tuning of parameters. The dynamical supersymmetry breaking sector contains nonrenormalizable interactions and vectorlike fields. Nonrenormalizable terms are characterized by the couplings of 0(1) in units of the Planck scale. The hierarchy of various mass scales in the model arises from the nonrenormalizable terms. The vacuum of this model conserves the color and electroweak symmetry. We also discuss a possible solution to the mu problem in this framework.
