摘要：

The solutions of anomalous Ward identities are used to determine the eta eta' mixing parameters theta(8) and theta(0) and the octet-singlet decay constants f(8) and f(0) in a U(3) x U(3) framework. Our results are fairly consistent with other recent findings for these quantities. We also enquire into the quark-flavor mixing scheme and obtain estimates for the corresponding decay constants defined in this basis.
