Phenomenological evidence for the gluon content of $\eta$ and $\eta$'
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\to 3\pi, J/\psi\to\eta\gamma and J/\psi\to\eta'\gamma in...
