Abstract
We classify SVOAs with no free fermions and with bosonic subalgebra a simply connected WZW algebra which is not of type . The latter restriction makes the classification tractable; the former restriction implies that the automorphism groups of the resulting SVOAs are finite. We discover two infinite families and nine exceptional examples. The exceptions are all related to the Leech lattice: their automorphism groups are the larger groups in the Suzuki chain (, , , , ) and certain large centralizers therein (, , , ). Along the way, we elucidate fermionic versions of a number of VOA operations, including simple current extensions, orbifolds, and ’t Hooft anomalies.
