Vertex Operators in 2K Dimensions
arXiv:hep-th/9503145 · doi:10.1103/PhysRevD.52.2462
Abstract
A formula is proposed which expresses free fermion fields in 2K dimensions in terms of the Cartan currents of the free fermion current algebra. This leads, in an obvious manner, to a vertex operator construction of nonabelian free fermion current algebras in arbitrary even dimension. It is conjectured that these ideas may generalize to a wide class of conformal field theories.
