Gravity in Causal Perturbative Quantum Field Theory
arXiv:2208.07043
Abstract
We extend the general framework of perturbative quantum field theory developped for the pure Yang-Mills model to gravity. First we present a variant of the elimination procedure of the anomalies in the second order of perturbation theory. After that we prove that gauge invariance restricts severely the possible finite renormalizations, so at least in the second order of the perturbation theory, the model is renormalizable.
