Consequences of Low Energy Dynamical Supersymmetry Breaking

Relatively simple models can be constructed in which supersymmetry is dynamically broken at energies of ${10}^5-{10}^7$ GeV. Models of this kind do not suffer from the naturalness and cosmological difficulties of conventional supergravity models, and make definite predictions for the spectrum of supersymmetric particle masses. Thus ``Renormalizable Visible Sector Models’’ are a viable alternative to more conventional approaches. This talk mostly summarizes the results of a recent paper written with Michael Dine and Yuri Shirman.
