QG4 |
Towards the graviton propagator from spinfoams |
Recently, interesting developments towards the costruction of the graviton perturbative expansion within the spinfoam formalism have appeared. Here we give a brief review of the results obtained, which include the right dependence on the spacetime distance of the free propagator, as well as an intriguing structure of the quantum corrections. |
