An interpretation of multigraviton amplitudes

Abstract
We obtain alternative expressions for the multigraviton tree level amplitudes and discuss their general properties. In particular, by analogy with Yang-Mills theory, we find that some combinatoric structure can be carried by a Chan-Paton factor of general relativity as a gauge theory.
