Disentangling the hadronic molecule nature of the $P_c(4380)$ pentaquark-like structure

We demonstrate that the relative ratio of the decays of hidden charm pentaquark-like structure $P_c^{+}(4380)$ to ${\bar{D}}^{\ast }{\mathrm{\Lambda }}_c^{+}$ and $J/\psi p$areverydifferentfor$P^+_c$being$\bar{D} \Sigma_c^(2520)$or$\bar{D}^ \Sigma_c(2455)$moleculestates\mathrm{.}Whilethepartialwidthofthe$\bar{D} \Sigma_c^(2520)$moleculetothe$\bar{D}^ \Lambda_c^+$ is much larger, by one order of magnitude, than that to the $J\mathrm{/}\psi p$, the $\bar{D}^* \Sigma_c(2455)$moleculeshowsadifferentpattern\mathrm{.}Ouranalysisshowsthatthe$\bar{D} \Sigma_c^$boundstateansatzismorereasonablethanthe$\bar{D}^ \Sigma_c$onetoexplainthebroad$P_c(4380)$ structure. We suggest to search for the $P_c(4380)$ in the ${\bar{D}}^{\ast }{\mathrm{\Lambda }}_c^{+}$ system, which can be used to disentangle the nature of the $P_c^{+}(4380)$ structure.
