Abstract

Conformal field theory is applied in the context of the o(16)×o(16) heterotic string. Branch cuts and unphysical operators are seen to appear in the operator-product expansions for certain physical fields. A four-fermion amplitude is calculated explicitly and found, nonetheless, to have correct physical behaviour.
