Theoretical description of the $\mathbf{J}/\mathbf{\psi }\to \mathbf{\eta }({\mathbf{\eta }}^{\prime }){\mathbf{h}}_1(1380)$, $\mathbf{J}/\mathbf{\psi }\to \mathbf{\eta }({\mathbf{\eta }}^{\prime }){\mathbf{h}}_1(1170)$ and $\mathbf{J}/\mathbf{\psi }\to {\mathbf{\pi }}^0{\mathbf{b}}_1(1235{)}^0$ reactions

Abstract

We have made a study of the $J/\psi \to {\eta }^{\prime }{h}_1,\eta h_1$ (with $h_1$ being $h_1(1170)$ and $h_1(1380)$) and $J/\psi \to {\pi }^0{b}_1(1235{)}^0$ assuming the axial vector mesons to be dynamically generated from the pseudoscalar-vector meson interaction. We have taken the needed input from previous studies of the $J/\psi \to \varphi \pi \pi ,\omega \pi \pi$ reactions. We obtain fair agreement with experimental data and provide an explanation on why the recent experiment on $J/\psi \to {\eta }^{\prime }{h}_1(1380),h_1(1380)\to K^{\ast +}{K}^{-}+c.c.$ observed in the $K^{+}{K}^{-}{\pi }^0$ mode observes the peak of the $h_1(1380)$ at a higher energy than its nominal mass.
