N = 1 curves for trifundamentals

We study the Coulomb phase of N = 1 SU(2)³ gauge theory coupled to one trifundamental field, and generalizations thereof. The moduli space of vacua is always onedimensional with multiple unbroken U(1) fields. We find that the N = 1 Seiberg-Witten curve which encodes the U(1) couplings is given by the double cover of a Riemann surface branched at the poles and the zeros of a meromorphic function.
