Description

We consider a special family of 4-d $\mathcal{N}=2$ superconformal theories, arising as orbifolds of $\mathcal{N}=4$ SYM under the action of a discrete group, realizing a circular quiver theory. Following the recent Gaberdiel-Gopakumar derivation, we construct a free field worldsheet theory in the tensionless string limit which is dual to the orbifold gauge theory at the free theory point. In particular, after imposing some specific gauge constraints on the worldsheet degrees of freedom, the spectrally flowed worldsheet spectrum is in one-to-one correspondence with the single trace operators of the free quiver theory at large $N$, realising the first step for the AdS/CFT correspondence in $\mathcal{N}=2$ framework in the full stringy regime.
