Superconformal index of low-rank gauge theories via the Bethe Ansatz
Superconformal index of low-rank gauge theories via the Bethe Ansatz
We study the Bethe Ansatz formula for the superconformal index, in the case of 4d $\mathcal{N}=4$ super-Yang-Mills with gauge group $SU(N)$. We observe that not all solutions to the Bethe Ansatz Equations (BAEs) contribute to the index, and thus formulate "reduced BAEs" such that all and only their solutions contribute. …
