Quarkyonic matter and chiral symmetry breaking in the Nambu-Jona–Lasinio model with Polyakov loops in large Nc — •Chihiro Sasaki1, Larry McLerran2, and Krzysztof Redlich3 — 1Dep. of Physics, Technische Universitaet Muenchen, Garching, Germany — 2Dep. of Physics, Brookhaven National Laboratory, Upton, USA — 3Institute for Theoretical Physics, University of Wroclaw, Wroclaw, Poland
The appearance of a new phase in dense QCD, quarkyonic matter, in the limit of large number of colors is studied within Nambu–Jona-Lassinio model coupled to Polyakov loops. The interplay of this novel phase with the chiral symmetry restoration and color deconfinement is discussed.
The model describes 3 phases (chirally broken, quarkyonic and chirally restored) in the confined phase. We show that in large Nc the phase diagram coincides with the one conjectured by McLerran and Pisarski. The Nc-dependence of chiral critical end point is also discussed.
