Abstract
We begin an investigation of supersymmetric theories based on exceptional groups. The flat directions are most easily parametrized using their correspondence with gauge-invariant polynomials. Symmetries and holomorphy tightly constrain the superpotentials, but due to multiple gauge invariants other techniques are needed for their full determination. We give an explicit treatment of and find gaugino condensation for ≤2, and an instanton generated superpotential for =3. The analogy with SU() gauge theories continues with modified and unmodified quantum moduli spaces for =4 and =5, respectively, and a non-Abelian Coulomb phase for ≥6. Electric variables suffice to describe this phase over the full range of . The Appendix gives a self-contained introduction to and its invariant tensors.
