Multi-Graviton Theories in the Causal Approach
arXiv:1703.10338
Abstract
The system of multi-gravitons has been considered before in the framework of functional formalism. We consider here the system of multi-gravitons in the causal formalism of quantum field theory. We derive in this formalism the fact that distinct gravitons cannot interact. The proof is based on a careful analysis of the first two orders of the perturbation theory.
