Description
Inspired by asymptotically free quantum gravity, we consider a nonlocal scalar field theory toy model that is ghost-free. We consider one-loop and two-loop Feynman diagrams and assess the divergence structure of those diagrams. We discuss the renormalizability of the theory, in contrast with General Relativity (GR). Finally, we indicate how our work will contribute to the establishment of a unitary, renormalizable theory of quantum gravity.
