Solving the anomalous Ward identities for the U(1) problem

Anomalous Ward identities are obtained for spontaneously realized SU(3) x SU(3) x U/sub 3/(1) in the presence of realistic symmetry-breaking quark mass terms in the Lagrangian. It is shown that the Ward identities contain more information than has hitherto been utilized. Together with low-energy the...

Zusammenfassung:Anomalous Ward identities are obtained for spontaneously realized SU(3) x SU(3) x U/sub 3/(1) in the presence of realistic symmetry-breaking quark mass terms in the Lagrangian. It is shown that the Ward identities contain more information than has hitherto been utilized. Together with low-energy theorems for ..pi../sup 0/, eta, and eta'..-->..2..gamma.. decays these provide a set of equations which are solved for the axial-vector couplings and topological-charge (or glueball) components of eta and eta'.
