| dc.description | A phenomenological analysis of radiative $V\to Pγ$ and $P\to Vγ$ decays is performed in order to determine the gluonic content of the $η^\prime$ wave function. Our result shows that there is no evidence for such a gluonium contribution, $Z_{η^\prime}^2=0.04\pm 0.09$. In terms of a mixing angle description this corresponds to $ϕ_P=(41.4\pm 1.3)^\circ$ and $|ϕ_{η^\prime G}|=(12\pm 13)^\circ$. | |
