On the critical end point of the QCD and the NJL model phase diagrams

TL;DR

This paper compares the understanding of the critical end point in the QCD phase diagram derived from lattice calculations and NJL model computations, highlighting similarities and differences in their predictions.

Contribution

It provides a comparative analysis of the critical end point predictions from lattice QCD and NJL models, clarifying their respective insights and limitations.

Findings

Lattice calculations suggest a specific location for the critical end point.

NJL models offer complementary predictions with certain approximations.

The comparison highlights areas where both approaches agree or diverge.

Abstract

In this talk I compare the knowledge on the critical end point of the QCD phase diagram grasped from lattice calculations, with that obtained from Nambu--Jona-Lasinio (NJL) model computations. The original publication is available at http://www.sif.it/SIF/en/portal/journals
