Needles in a haystack: An algorithmic approach to the classification of 4d $\mathcal{N}=2$ SCFTs

Justin Kaidi, Mario Martone, Leonardo Rastelli +1

There is a well-known map from 4d $\mathcal{N}=2$ superconformal field theories (SCFTs) to 2d vertex operator algebras (VOAs). The 4d Schur index corresponds to the VOA vacuum char…
