Journal ArticleDOI
Color superconductivity in dense quark matter
TL;DR: The color-flavor locked (CFL) phase as mentioned in this paper is a color superconductor, which is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the surface that induces color Meissner effects.
Journal ArticleDOI
QCD at finite baryon density: nucleon droplets and color superconductivity
TL;DR: In this article, a variational procedure was used to study finite-density QCD in an approximation in which the interaction between quarks is modelled by that induced by instantons, and it was shown that uniform states with conventional chiral symmetry breaking have negative pressure with respect to empty space at all but the lowest densities.
Journal ArticleDOI
Color-flavor locking and chiral symmetry breaking in high density QCD
TL;DR: In this paper, a symmetry breaking scheme for QCD with three massless quarks at high baryon density was proposed, where the color and flavor SU(3) color × SU (3) L × SU( 3) R symmetries were broken down to the diagonal subgroup SU(4) color+L + R by the formation of a condensate of quark Cooper pairs.
Journal ArticleDOI
Signatures of the Tricritical Point in QCD
TL;DR: In this article, a combination of event-by-event observables, including suppressed fluctuations in T and baryon chemical potential {mu} and, simultaneously, enhanced fluctuations in the multiplicity of soft pions, is proposed to identify the tricritical point on the boundary of the phase with spontaneously broken chiral symmetry.
Journal ArticleDOI
Event-by-Event Fluctuations in Heavy Ion Collisions and the QCD Critical Point
TL;DR: In this paper, the authors studied the thermodynamic properties of the hadronic system at freeze-out and found that those event-by-event signatures which are characteristic of freezeout in the vicinity of the critical point exhibit non-monotonic dependence on control parameters.
