Description
We study the Higgs branch and VOA of 4d N=2 SCFTs from the geometric engineering of IIB superstring on canonical threefold singularities. We cover examples of terminal singularities as well as hypersurface singularities with smooth or singular exceptional divisors in their crepant resolution. We found many new VOAs with no known W-algebra descriptions, as well as examples of 4d N=2 SCFTs with the E-type Kleinian singularities as their Higgs branches.
