Abstract :
We calculate the superconformal index for image Chern–Simons-matter theory with gauge group image at arbitrary allowed value of the Chern–Simons level k. The calculation is based on localization of the path integral for the index. Our index counts supersymmetric gauge invariant operators containing inclusions of magnetic monopole operators, where latter operators create magnetic fluxes on 2-sphere. Through analytic and numerical calculations in various sectors, we show that our result perfectly agrees with the index over supersymmetric gravitons in image in the large N limit. Monopole operators in nontrivial representations of image play important roles. We also comment on possible applications of our methods to other superconformal Chern–Simons theories.
