摘要：

We discuss the effect of eta-eta' mixing and of axial current anomalies on various decay processes. We describe the 2 gamma decays of eta and eta' the radiative decays of low-lying vector mesons as well as the decays eta --> 3 pi, J/psi --> eta gamma and J/psi --> eta'gamma in one unified framework, in which they are related to the electromagnetic and strong axial current anomalies, respectively. We also discuss briefly the enhancement of eta' in D-s decays and suggest a possible relation to gluon-mediated processes. The importance of the decays of the glueball candidates f(0)(1500) and f(0)(1590) into eta eta' channels is also stressed.
