Branes, Orbifolds and the Three Dimensional $\mathcal{N}=2$ SCFT in the Large N limit

Abstract

We study the correspondence between the large $N$ limit of $\mathcal{N}=2$ three dimensional superconformal field theories and M theory on orbifolds of $Ad{S}_4\times {\mathbf{S}}^7$. We identify the brane configuration which gives $C^3/Z_3$ as a background for the M theory in terms of a Brane Box Model or a (p, q) web model. By taking the orbifold projection on the known spectrum of Kaluza-Klein harmonics of supergravity, we obtain information about the chiral primary operators at the orbifold singularities.
