Matrix models and Multitrace Superpotentials

 
It has recently been realized that superpotentials for certain N=1
supersymmetric field theories can be computed from the large N
imit of an associated  matrix model. Specifically, the example best
understood is N=1 supersymmetric U(N) theory with adjoint
matter and a single trace tree level superpotential. We generalize
the setup to include multi-trace tree level superpotential. The
prescription to extract the non-perturbative superpotentials differs
in important respects from that of Dijkgraaf and Vafa for single trace
superpotentials.
