On the 4D SCFTs/VOAs correspondence

Leonardo Rastelli , Stony Brook University

I will describe some recent progress on the correspondence between four-dimensional N=2 superconformal field theories (SCFTs) and two-dimensional vertex operator algebras (VOAs). In particular I will introduce the notion of the “Higgs scheme”, an extension by nilpotent elements of the standard Higgs variety of an N=2 SCFT, which plays a natural role in the associated VOA. Unlike the Higgs variety, theHiggs scheme appears to be a perfect invariant, i.e. it conjecturally fully characterizes the SCFT.
