摘要：

In the IR limit the Matrix string theory is expected to be described by the (SR8)-R-N supersymmetric orbifold sigma model. Recently Dijkgraaf, Verlinde and Verlinde proposed a vertex that may describe the type IIA string interaction. In this paper using this interaction vertex we derive the four graviton scattering amplitude from the orbifold model in the large N limit. (C) 1998 Published by Elsevier Science B.V.
