Three dimensional Mirrors from IR N-ality

Abstract

We discuss an explicit field theory construction of three dimensional mirrors for a large sub-class of quiver gauge theories involving unitary and special unitary gauge nodes with matter in fundamental and bifundamental representations. For this sub-class of theories, one can deploy a sequence of IR dualities and certain Abelian field theory operations to reduce the aforementioned problem to a problem of finding the 3d mirror of a simpler unitary quiver gauge theory. We illustrate the construction with a linear quiver consisting of unitary and special unitary gauge nodes.
