dc.descriptionOne-loop calculations in quantum gravity coupled to U(1)-Abelian fields (photon fields) are ultraviolet finite and cutoff-free in the framework of causal perturbation theory. We compute the photon loop correction to the graviton propagator and the photon self-energy in second order perturbation theory. Perturbative gauge invariance to second order is shown and generates the gravitational Slavnov-Ward identities.
