LQG propagator from the new spin foams
arXiv:0905.4082 · doi:10.1016/j.nuclphysb.2009.07.016
Abstract
We compute metric correlations in loop quantum gravity with the dynamics defined by the new spin foam models. The analysis is done at the lowest order in a vertex expansion and at the leading order in a large spin expansion. The result is compared to the graviton propagator of perturbative quantum gravity.
