Quarkyonic Matter and the Phase Diagram of QCD

TL;DR

This paper discusses the concept of Quarkyonic matter as a novel phase of QCD at finite temperature and density, supported by theoretical arguments and experimental hints, expanding understanding of the QCD phase diagram.

Contribution

It introduces Quarkyonic matter as a distinct phase in QCD and provides evidence for its existence in real-world QCD through lattice data and experiments.

Findings

Hints of Quarkyonic matter in lattice QCD data

Experimental indications from heavy ion collisions

Theoretical support in the large N_c limit

Abstract

Quarkyonic matter is a new phase of QCD at finite temperature and density which is distinct from the confined and de-confined phases. Its existence is unambiguously argued in the large number of colors limit in QCD. Hints of its existence for 3 color QCD are shown in lattice Monte-Carlo data and heavy ion experiments.
