Higher Order Graviton Scattering in M(atrix) Theory

arXiv:hep-th/9706072 · doi:10.1103/PhysRevD.56.R3174

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 $v^{6} / r^{14}$ term, a two-loop effect, in agreement with explicit matrix model calculation.
