Sub-leading asymptotic behaviour of area correlations in the Barrett-Crane model

Understand

The Barrett-Crane spin foam model for quantum gravity provides an excellent setting for testing analytical and numerical tools used to probe spinfoam models.

• Here, we complete the report on the numerical analysis of the single 4-simplex area correlations begun in Phys.

• B670 (2009) 403-406, discussing the next-to-leading order corrections ("one-loop" corrections) with particular attention to their measure dependence, and the difference between the Gaussian and Bessel ansatze for the boundary state.
