Color-Flavor Locking and Chiral Symmetry Breaking in High Density QCD
We propose a symmetry breaking scheme for QCD with three massless quarks at high baryon density wherein the color and avor 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 excitation...
متن کاملThe Color–Flavor Transformation of induced QCD
The color–flavor transformation is applied to the U(Nc) lattice gauge model, in which the gauge theory is induced by a heavy chiral scalar field sitting on lattice sites. The flavor degrees of freedom can encompass several ‘generations’ of the auxiliary field, and for each generation, remaining indices are associated with the elementary plaquettes touching the lattice site. The effective, color...

متن کاملTwo-flavor QCD simulation with exact chiral symmetry
We perform numerical simulations of lattice QCD with two flavors of dynamical overlap quarks, which have exact chiral symmetry on the lattice. While this fermion discretization is computationally demanding, we demonstrate the feasibility to simulate reasonably large and fine lattices by a careful choice of the lattice action and algorithmic improvements. Our production runs are carried out on a...
متن کاملColor Superfluidity and Chiral Symmetry Breakdown in Dense Qcd Matter
We describe the interplay of two nonperturbative phenomena which should take place in the chirally invariant deconfined phase of QCD matter at finite density and T=0 : (i) Cooper-pair quark-quark ground-state condensation in appropriate channels should yield exotic sorts of color superfluidity, and (ii) quark-antiquark ground-state condensation should yield spontaneous breakdown of chiral symme...
