Exact results and duality for Sp(2N) SUSY gauge theories with an antisymmetric tensor

We study supersymmetric Sp(2N) gauge theories with matter in the antisymmetric tensor representation and F fundamentals. For F = 6 we solve the theory exactly in terms of confined degrees of freedom and a superpotential. By adding mass terms we obtain the theories with F < 6 which we find to exhibit a host of interesting non-perturbative phenomena: quantum-deformed moduli spaces with N constraints, instanton-induced superpotentials and non-equivalent disjoint branches of moduli spaces. We find a simple dual for F = 8 and no superpotential. We show how the F = 4 and F = 2 theories can be modified to break supersymmetry spontaneously and point out that the Sp(6) theory with F = 6 may be very interesting for model builders.
