BCFW construction of the Veneziano Amplitude

arXiv:1010.6265 · doi:10.1088/1751-8113/44/23/235402

Abstract

In this note we demonstrate how one can compute the Veneziano amplitude for bosonic string theory using the BCFW method. We use an educated ansatz for the cubic amplitude of two tachyons and an arbitrary level string state.
