Quantum gravity coupled to scalar massive matter fields is investigated in the framework of causal perturbation theory using the Epstein Glaser regularizationΓrenormalization scheme. Detailed one-loop calculations include the matter loop graviton self-energy and the matter self-energy. The condition
We give a general procedure for extracting the propagators in gauge theories in the presence of a sharp galuge fixing and we apply it to derive the propagators in quantum gravity in the radial gauge, both in the first- and in the second-order formalism in any space-time dimension. In the threc-dimen
