Counting Exceptional Instantons

arXiv:1205.4722 · doi:10.1007/JHEP07(2012)085

Abstract

We show how to obtain the instanton partition function of N=2 SYM with exceptional gauge group EFG using blow-up recursion relations derived by Nakajima and Yoshioka. We compute the two instanton contribution and match it with the recent proposal for the superconformal index of rank 2 SCFTs with E6, E7 global symmetry.
