Abstract
Models with dynamical supersymmetry breaking are interesting because t hey may provide a solution to both the gauge hierarchy and the fine-tu ning problems. However, because of strongly interacting dynamics, it i s in general impossible to analyze them quantitatively. One of the few models with calculable dynamical supersymmetry breaking is a model wi th SU(5) gauge symmetry and two 10's and two <(5)over bar 's> as the m atter content. We determine the ground state of this model, find the v acuum energy, reveal the symmetry breaking pattern and calculate the m ass spectrum. The supertrace mass relation is exploited to verify the consistency of the calculated mass spectrum, and an accidental degener acy is explained.
