• W4200612934 abstract "Very recently, the LHCb collaboration released the newest measurements of ${B}_{s}ensuremath{rightarrow}J/ensuremath{psi}poverline{p}$, where an enhancement structure near 4.34 GeV was observed in the invariant mass spectrum of $J/ensuremath{psi}p$ with the statistical significance of $3.1--3.7ensuremath{sigma}$. In this work, by performing a combined analysis for the three invariant mass spectra of ${B}_{s}ensuremath{rightarrow}J/ensuremath{psi}poverline{p}$, we find that this $J/ensuremath{psi}p$ structure near 4.34 GeV can correspond to the contributions from the ${P}_{c}(4380{)}^{+}$ state with the assumption of ${J}^{P}=3/{2}^{ensuremath{-}}$ together with the reflections of ${B}_{s}ensuremath{rightarrow}({f}_{2}^{*}ensuremath{rightarrow}poverline{p})J/ensuremath{psi}$. Here, ${P}_{c}(4380)$ was first observed in ${mathrm{ensuremath{Lambda}}}_{b}ensuremath{rightarrow}J/ensuremath{psi}pK$ but not confirmed in the updated LHCb data in 2019, and ${f}_{2}^{*}$ means the exciting light isoscalar tensor meson around 2.0 GeV. Thus, this provides a possible evidence to support the existence of the pentaquark ${P}_{c}(4380)$. Specifically, the assumed spin parity ${J}^{P}=3/{2}^{ensuremath{-}}$ of ${P}_{c}(4380)$ is consistent with a prediction of the theoretical explanation of an $S$-wave $overline{D}{mathrm{ensuremath{Sigma}}}_{c}^{*}$ molecular bound state." @default.
