Description
We identify all possible N=1 supersymmetric gauge theories that are generically in the Coulomb phase, i.e. susy theories without a tree level superpotential that are broken down to U(1) or a product of U(1)s at generic points on the moduli space. Analogous to the Seiberg-Witten solution of N=2 gauge theories, the low energy theory is that of a photon (or several photons); its coupling can be found exactly and its value at various points on the moduli space is encoded in an elliptic curve. In this talk, we focus on one of the new N=1 Coulomb phase theories and find that a suitable deformation leads to dynamical breaking of supersymmetry. Perhaps surprisingly, susy can still be broken without lifting all classical flat directions. In the susy breaking minima of our theory, magnetic monopoles in the dual description condense, signaling confinement in terms of the original variables. We provide some brief speculations into the nature of confinement at these points.
