D=11 SUGRA as the low energy effective action of matrix theory: three formscattering

We employ the LSZ reduction formula for matrix theory introduced in our ear lier work to compute the t-pole S-matrix for three form-three form scatteri ng. The result agrees completely with tree level D = 11 SUGRA. Taken togeth er with previous results on graviton-graviton scattering this shows that ma trix theory indeed reproduces the bosonic sector of the D = 11 SUGRA action including the Chern-Simons term. Furthermore we provide a detailed account of our framework along with the technology to compute any matrix theory on e-loop t-pole scattering amplitude at vanishing p(-) exchange.
