John W. Barrett, Richard J. Dowdall, Winston J. Fairbairn, Henrique, Gomes, Frank Hellmann
TL;DR
This paper reviews the asymptotic analysis of the Euclidean EPRL spin foam model using coherent states, focusing on conceptual issues for Immirzi parameter less than one, and omitting peripheral proofs.
Contribution
It provides a conceptual overview of the asymptotic analysis of the EPRL model, clarifying key steps and issues for the Euclidean sector with Immirzi parameter less than one.
Findings
Clarified the conceptual framework of asymptotic analysis for the EPRL model.
Summarized the main steps in using coherent states for the analysis.
Omitted peripheral proofs and spin structure discussions.
Abstract
We review the basic steps in building the asymptotic analysis of the Euclidean sector of new spin foam models using coherent states, for Immirzi parameter less than one. We focus on conceptual issues and by so doing omit peripheral proofs and the original discussion on spin structures.
