A Simple Complete Model of Gauge-Mediated SUSY-Breaking and Dynamical Relaxation Mechanism for Solving the $\mu$-Problem

In this paper two things are done. First, we propose a simple model of dynamical gauge-mediated SUSY breaking. This model incorporates a mechanism in which the \mu-problem is solved by a dynamical relaxation mechanism which involves no light fields beyond those of the MSSM. In the second part of the paper we show how this mechanism is generalized and give two more examples in which it is incorporated.
