A Bethe Ansatz type formula for the superconformal index
arXiv:1811.04107 · doi:10.1007/s00220-019-03679-y
Abstract
Inspired by recent work by Closset, Kim and Willett, we derive a new formula for the superconformal (or supersymmetric) index of 4d N=1 theories. Such a formula is a finite sum, over the solution set of certain transcendental equations that we dub Bethe Ansatz Equations, of a function evaluated at those solutions.
