1210.1776 (Yung-Yeh Chang et al.)

A note on on-shell recursion relation of string amplitudes    [PDF]

Yung-Yeh Chang, Bo Feng, Chih-Hao Fu, Jen-Chi Lee, Yihong Wang, Yi Yang
In the application of on-shell recursion relation to string amplitudes, one challenge is the sum over infinite intermediate on-shell string states. In this note, we show how to sum these infinite states explicitly by including unphysical states to make complete Fock space.
