Abstract

We give a Seiberg-like dual description of the interacting superconformal infrared fixed point of N=4 gauge theory in three dimensions with vanishing Chern Simons level and N_c≤ N_f<2N_c fundamental flavors. These theories are known as "bad" theories due to the existence of unitarity violating monopole operators. We show that, in a dual description, all such operators are realized by free fields and the remainder theory is the Seiberg-like dual previously identified using the type IIB brane construction.
