Description
In heavy quarkonia, hadronic transitions serve as an enlightened probe for the structure and help to establish the understanding of light quark coupling with heavy degree of freedom. We propose a new model to create light meson(s) in heavy quarkonium transitions, which is inspired by Nambu-Jona-Lasinio model. The model shows its potential to reproduce the observed decay widths and make predictions for the unobserved channels. In this contribution, we present our predictions for the hidden-charm decays of higher $S$ and $D$ wave vector charmonia. We also suggest $J^{PC}$ assignments for several experimentally observed vector charmonium-like states. We hope that our predictions [1] might provide useful references to determine the properties of higher charmonia in ongoing and forthcoming experiments.
