Color flavor locking and chiral symmetry breaking in high density QCD

  title={Color flavor locking and chiral symmetry breaking in high density QCD},
  author={Mark G. Alford and Krishna Rajagopal and Frank Wilczek},
  journal={Nuclear Physics},
Abstract We propose a symmetry breaking scheme for QCD with three massless quarks at high baryon density wherein the color and flavor SU(3) color × SU(3) L × SU(3) R symmetries are broken down to the diagonal subgroup SU(3) color+ L + R by the formation of a condensate of quark Cooper pairs. We discuss general properties that follow from this hypothesis, including the existence of gaps for quark and gluon excitations, the existence of Nambu-Goldstone bosons which are excitations of the diquark… Expand

High-density QCD and instantons
Abstract Instantons generate strong nonperturbative interactions between quarks. In vacuum, these interactions lead to chiral symmetry breaking and generate constituent quark masses on the order ofExpand

Kaon condensation in the color–flavor-locked phase of quark matter, the Goldstone theorem, and the 2PI Hartree approximation
Abstract At very high densities, QCD is in the color–flavor-locked phase, which is a color-superconducting phase. The diquark condensates break chiral symmetry in the same way as it is broken inExpand
Generalized mesons in dense QCD
Abstract QCD superconductors in the color–flavor-locked (CFL) phase support excitations (generalized mesons) that can be described as pairs of particles or holes (rather than particle–hole) around aExpand
Patterns of Symmetry Breaking in QCD at High Baryon Density
We study the structure of QCD at very large baryon density for an arbitrary number of flavors Nf. We provide evidence that for any number of flavors larger than Nf=2 chiral symmetry remains broken atExpand
Bulk viscosity in kaon-condensed color–flavor-locked quark matter
Color–flavor-locked (CFL) quark matter at high densities is a color superconductor, which spontaneously breaks baryon number and chiral symmetry. Its low-energy thermodynamic and transport propertiesExpand

Abstract We examine the role of instantons in the zero-temperature chiral phase transition in an SU(N) gauge theory. For a range of Nf (the number of fermion flavors) depending on N, the theoryExpand
