We study N=1 supersymmetric SU(N) gauge theories with n_f fundamental flavors and (n_f-N+4) anti-fundamental flavors along with an anti-symmetric gauge tensor, we find IR dual theories depending on n_f by using a set of known dualities.
First we present a proof of the duality for a special number of flavors inspired by a mathematical equality which we interpret as an equality between two super-conformal indices, based on this we branch off to a duality which is valid for a range of flavor numbers. |
