================================

Most of these papers have been discussed some already in PF threads. One however was just posted at arxiv today. Since it may not be already known, I'll give the abstract for it:

LQG propagator: III. The new vertex

Emanuele Alesci, Eugenio Bianchi, Carlo Rovelli

"In the first article of this series, we pointed out a difficulty in the attempt to derive the low-energy behavior of the graviton two-point function, from the loop-quantum-gravity dynamics defined by the Barrett-Crane vertex amplitude. Here we show that this difficulty disappears when using the corrected vertex amplitude recently introduced in the literature. In particular, we show that the asymptotic analysis of the new vertex amplitude recently performed by Barrett, Fairbairn and others, implies that the vertex has precisely the asymptotic structure that, in the second article of this series, was indicated as the key necessary condition for overcoming the difficulty."
