Do New Spinfoam Models Have a Good Semiclassical Limit?

[ensabah6]

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.
