“…Besides mass spectra and production, strong decay behaviors reflect the internal structures of charmoniumlike states and hence have been attracting increasing attention. In literature, two-meson decay channels have been widely studied [11][12][13][14][15][16][17][18][19][20][21][22][23]. For molecular states, these decays usually occur through meson exchange processes, and the fall-apart mechanism is generally assumed to estimate the partial decay widths of compact tetraquarks.…”

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 the four-body systems, and we calculate the pion/kaon emissions of the $X(4700)$, $Z_c(4430)$, $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ within the compact tetraquark assumptions. It is found that the pion/kaon decay widths for the $X(4700)$ and $Z_c(4430)$ are relatively small, while the partial decay widths for the resonances $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ are significant. We expect that our exploration of these decay behaviors can provide useful information for future experimental searches and theoretical interpretations.

There may exist seven Dbar(*)Σc (*) hadronic molecular states. We construct their corresponding interpolating currents, and calculate their masses and decay constants using QCD sum rules. Based on these results, we calculate their relative production rates in Λb 0 decays through the current algebra, i.e., B(Λb 0 → Pc K-):B(Λb 0 → Pc' K-) with Pc and Pc' two different states. We also study their decay properties through the Fierz rearrangement, and further calculate these ratios in the J/ψp mass spectrum, i.e. B(Λb 0 → Pc K- → J/ψ p K-):B(Λb 0 → Pc' K- → J/ψ p K-). Our results suggest that the Dbar*Σc * molecular states of J(P) = 1/2(-) and 3/2(-) are possible to be observed in future experiments.
