Título: "From the graviton to gravity"

Abstract:

We try to lift a corner of the veil covering "dequantization", in the
realm of gravitational theory. As it happens, quantum gravitational interactions involve more complication that just the coupling of
stress-energy-momentum tensor to gravitons. A rigorous approach based
on the autonomous formulation of QFT demands graviton's self-interaction, leading to the (perturbative development of) Einstein's action.
