SOME EXAMPLES OF CHIRAL MODULI SPACES AND DYNAMICAL SUPERSYMMETRY BREAKING

We investigate the low-energy dynamics of SU(N) gauge theories with on e antisymmetric tensor field, N - 4 + N-f antifundamentals and N-f fun damentals, for N-f less than or equal to 3. For N-f = 3 we construct t he quantum moduli space, and for N-f < 3 we find the exact quantum sup erpotentials. We find two large classes of models with dynamical super symmetry breaking. The odd N theories break supersymmetry once appropr iate mass terms are added in the superpotential. The even N theories b reak supersymmetry after gauging an extra chiral U(1) symmetry.
