Abstract
We adopt the quark pair creation model to investigate the light meson emissions of several charmonium-like states. The quark pair creation model is applied to four-body systems, and we calculate the pion/kaon emissions of , , , , , and within compact tetraquark configurations. We find that the pion/kaon decay widths of and are relatively small, whereas the partial decay widths of the resonances , , , and are significant. We expect that our exploration of these decay behaviors will provide useful information for future experimental searches and theoretical interpretations.
