Worldsheet dual of free $$ \mathcal{N} $$ = 2 quiver gauge theories

Abstract

Abstract For a special family of 4d $$ \mathcal{N} $$ N = 2 superconformal quiver theories, the worldsheet dual corresponding to the free theory is identified. This result is obtained from the recently proposed worldsheet dual of free $$ \mathcal{N} $$ N = 4 SYM by applying a ℤk orbifold. In support of our proposal we show that the spectrum of both the untwisted as well as the twisted sectors coincides between the two descriptions.
