• W2290793945 abstract "We study the strong decay channels ${P}_{c}^{+}(4380)ensuremath{rightarrow}J/ensuremath{psi}p$ and ${P}_{c}^{+}(4450)ensuremath{rightarrow}J/ensuremath{psi}p$ under a ${mathrm{ensuremath{Sigma}}}_{c}{overline{D}}^{*}$ molecular state ansatz. With various spin-parity assignments, the partial decay widths of the $J/ensuremath{psi}p$ final state are calculated. Our results show that all the $P$ wave ${mathrm{ensuremath{Sigma}}}_{c}{overline{D}}^{*}$ assignments are excluded, while $S$ wave ${mathrm{ensuremath{Sigma}}}_{c}{overline{D}}^{*}$ pictures for ${P}_{c}(4380)$ and ${P}_{c}(4450)$ are both allowed by present experimental data. The ${J}^{P}=3/{2}^{ensuremath{-}}$ ${mathrm{ensuremath{Sigma}}}_{c}^{*}overline{D}$ and ${mathrm{ensuremath{Sigma}}}_{c}^{*}{overline{D}}^{*}$ molecules are also discussed in the heavy quark limit, and we find that the ${mathrm{ensuremath{Sigma}}}_{c}^{*}overline{D}$ system for ${P}_{c}(4380)$ is possible. More experimental information on spin parities and partial decay widths and theoretical investigations on other decay modes are needed to clarify the nature of the two ${P}_{c}$ states." @default.
