Particle scattering in loop quantum gravity

TL;DR

A tentative implementation of a technique for defining and computing -point functions in the context of a background-independent gravitational quantum field theory in a perturbatively finite model defined using spin foam techniques in thecontext of loop quantum gravity is constructed.

Abstract

We devise a technique for defining and computing n-point functions in the context of a background-independent gravitational quantum field theory. We construct a tentative implementation of this technique in a perturbatively-finite loop/spinfoam model.
