Light meson emissions of selected charmonium-like states within compact tetraquark configurations

We adopt the quark pair creation model to investigate the light meson emissions of several charmoniumlike states. The quark pair creation model is applied to four-body systems, and we calculate the pion/kaon emissions of X(4700), Z(c)(4430), Y(4230), Y(4360), Y(4390), and Y(4660) within compact tetraquark configurations. We find that the pion/kaon decay widths of X(4700) and Z(c)(4430) are relatively small, whereas the partial decay widths of the resonancesY(4230), Y(4360), Y(4390),and Y(4660) are significant. We expect that our exploration of these decay behaviors will provide useful information for future experimental searches and theoretical interpretations.
