Abstract
The requirement that matrix elements of current commutators are saturated by single-particle intermediate states leads to kinematical restrictions on the allowed momenta of these states. For the algebra the momentum must be zero, while for the chiral algebra it must be infinite. In this single-particle limit it is shown that the chiral algebra is equivalent to the collinear subalgebra of , and so a relation between the and chiral algebras is established.
