Effects of density-dependent quark mass on phase diagram of three-flavor quark matter
Considering the density dependence of quark mass, we investigate the phase transition between the ( unpaired ) strange quark matter and the color-flavor-locked matter, which are supposed to be two candidates for the ground state of strongly interacting matter. We find that if the current mass of strange quarkms is small, the strange quark matter remains stable unless the baryon density is very ...
متن کاملNeutral Dense Quark Matter
The ground state of dense up and down quark matter under local and global charge neutrality conditions with β-equilibrium has at least four possibilities: normal, regular 2SC, gapless 2SC phases, and mixed phase composed of 2SC phase and normal components. The discussion is focused on the unusual properties of gapless 2SC phase at zero as well as at finite temperature.
متن کاملPhase Diagram of Neutral Quark Matter at Moderate Densities
We discuss the phase diagram of moderately dense, locally neutral three-flavor quark matter using the framework of an effective model of quantum chromodynamics with a local interaction. The phase diagrams in the plane of temperature and quark chemical potential as well as in the plane of temperature and lepton-number chemical potential are discussed.

We study the phase diagram of dense, locally neutral three-flavor quark matter as a function of the strange quark mass, the quark chemical potential, and the temperature, employing a general nine-parameter ansatz for the gap matrix. At zero temperature and small values of the strange quark mass, the ground state of matter corresponds to the color-flavor-locked (CFL) phase. At some critical valu...
متن کاملChromomagnetic Instability and Gluonic Phase in Dense Neutral Quark Matter
The phase structure of hot and/or dense QCD is one of the most exciting current topics in the field of strong interactions. In particular, the properties of cold and dense quark matter are of great interest in astrophysics and cosmology; it is now widely accepted that, at moderate densities of relevance for the interior of compact stars, quark matter is a color superconductor and has a rich pha...
