Does the new spinfoam models have a good semiclassical low energy large volume limit?

    By new I mean the new connections Rovelli have discussed as spinfoam 4d now talks to LQG.

    Not know yet. Work is in progress.

    Rovelli speaks of LQG dynamics as non-transparent, spinfoam dynamics as transparent.

    The newer SF models in 4D have an immirizi parameter and the kinematics matches LQG.
