Gerbal central extensions of reductive groups by K 3

We classify central extensions of a reductive group G by K 3 and B K 3 , the sheaf of third Quillen K-theory groups and its classifying stack. These turn out to be parametrized by the group of Weyl-invariant quadratic forms on the cocharacter lattice valued in k × and the group of integral Weyl-inva...
