Quark-Antiquark Condensates Break Chiral Symmetry
نویسنده
چکیده
In the physical vacuum of QCD, the energy density of lightquark fields strongly coupled to slowly varying gluon fields can be negative. The states that drive this energy density lowest are condensates of pairs of quarks and antiquarks of nearly opposite momenta. These quark-antiquark condensates break chiral symmetry.

متن کاملDynamical Higgs Mechanism without Elementary Scalars: A Lesson from Instantons
The generation of gauge–dependent fermion vacuum condensates in Yang– Mills theory would dynamically break the gauge symmetry and thus provide an alternative to the Higgs mechanism in unified theories. We explore a simple example: instanton-induced quark pair (diquark) condensation in QCD with 2 flavors and Nc colors. We do find diquark condensates in the vacuum, but only for Nc = 2, where they...
متن کاملQuark description of nuclear matter Jürgen
We discuss the role of an adjoint chiral condensate for color superconducting quark matter. Its presence leads to color-flavor locking in two-flavor quark matter. Color is broken completely as well as chiral symmetry in the two-flavor theory with coexisting adjoint quark-antiquark and antitriplet quark-quark condensates. The qualitative properties of this phase match the properties of ordinary ...
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...
