The superconformal index of the \(E_{6}\) SCFT. (English) Zbl 1290.81064

Summary: We derive an integral representation for the superconformal index of the strongly-coupled \( \mathcal{N} = 2 \) superconformal field theory with \(E_{6}\) flavor symmetry. The explicit expression of the index allows highly non-trivial checks of Argyres-Seiberg duality and of a class of S-dualities conjectured by Gaiotto.
