Description
We have made a study of the $J/\psi\rightarrow\eta'h_1$, $\eta h_1$ (with $h_1$ being $h_1 (1170)$ and $h_1 (1380)$), $J/\psi\rightarrow\pi^0 b_1 (1235)^0$ and $\chi_{cJ}\rightarrow \phi h_1(1380)$ assuming the axial vector mesons to be dynamically generated from the pseudoscalar-vector meson interaction.
For the $J/\psi$ decays, we obtain fair agreement with experimental data and provide an explanation on the recent BESIII measurement on $K\bar{K}\pi$ distribution in $J/\psi\rightarrow\eta'h_1(1380)$, $h_1(1380)\rightarrow K^{*+}K^{-} + c.c.$.
For the $\chi_{cJ}$ decay, the molecular picture of $h_1(1380)$ can easily explain the difference of $\chi_{c0}$ and $\chi_{c1,2}$ production and a dip seen in the $K^+\pi^0K^-$ distribution observed by BESIII Collaboration.
