3d dualities from 2d free field correlators: recombination and rank stabilization

Abstract

We propose various new 3d mathcal{N} = 2 dualities exploiting their recently discovered connection to the duality relations for 2d free field CFT correlators. Most of the dualities involve, as the main building block, a quiver theory with monopole superpotential which enjoys various interesting properties such as being self-dual and reducing, in a suitable real mass deformation, to the familiar T [SU(N )] theory. In particular we propose a duality for the U(N) theory with one adjoint and k + 1 fundamental flavors. By iterating some basic dualities we can bring the theory to a stable form which, in turns, allows us to find a dual frame where the rank of the original theory appears as a parameter.
