Chiral-SU(3)-symmetry breaking for the pseudoscalar mesons

In the framework of the quark--vector-gluon model, with chiral symmetry broken by a quark mass term, careful use of the algebraic properties of the Hamiltonian and of the divergences of axial-vector currents leads to a consistent picture of symmetry breaking in the pseudoscalar nonet. The eta'(...

Beschreibung
Zusammenfassung:	In the framework of the quark--vector-gluon model, with chiral symmetry broken by a quark mass term, careful use of the algebraic properties of the Hamiltonian and of the divergences of axial-vector currents leads to a consistent picture of symmetry breaking in the pseudoscalar nonet. The eta'(960) emerges with a large gluon component. (AIP)
