Abstract

Free string theory on the plane‐wave background displays a discrete Z~2~ symmetry exchanging the two transverse SO(4) groups. This symmetry should be respected also at the interacting level. We show that the zero mode structure proposed in hep‐th/0208148 can be completed to a full kinematical vertex, contrary to claims appeared in the previous literature. We also comment on the relation with recent works on the string‐bit formalism and on the comparison with the field theory side of the correspondence.
