Generalized OnShell Ward Identities in String Theory
Abstract
It is demonstrated that an infinite set of stringtree level on shell Ward identities, which are valid to all σmodel loop orders, can be systematically constructed without referring to the string field thoery. As examples, bosonic massive scattering amplitudes are calculated explicitly up to the second massive excited states. Ward identities satisfied by these amplitudes are derived by using zeronorm states in the spectrum. In particulalr the interparticle Ward identity generated by the D_{2} otimes D_{2'} zeronorm state at the second massive level is demonstrated. The four physical propagating states of this mass level are then shown to form a large gauge multiplet. This result justifies our previous consideration on higher interspin symmetry from the generalized worldsheet σmodel point of view.
