Higher Order Graviton Scattering in M(atrix) Theory
K. Becker, M. Becker, J. Polchinski, A. Tseytlin
Abstract
In matrix theory the effective action for graviton-graviton scattering is a double expansion in the relative velocity and inverse separation. We discuss the systematics of this expansion and subject matrix theory to a new test. Low energy supergravity predicts the coefficient of the v6/r14 term, a two-loop effect, in agreement with explicit matrix model calculation.
