Quarkyonic Matter and the Revised Phase Diagram of QCD

Abstract

At high baryon number density, it has been proposed that a new phase of QCD matter controls the physics. This matter is confining but can have densities much larger than ${\Lambda }_{QCD}^3$ QCD. Its existence is argued from large Nc approximations, and model computations. It is approximately chirally symmetric.
