Abstract
Motivated by the successful interpretation of these observed ${P}_{c}$ and ${P}_{cs}$ states under the meson-baryon molecular picture, we systematically investigate the possible hidden-charm molecular pentaquark states with triple strangeness which is due to the ${\mathrm{\ensuremath{\Omega}}}_{c}^{(*)}{\overline{D}}_{s}^{(*)}$ interactions. We perform a dynamical calculation of the possible hidden-charm molecular pentaquarks with triple strangeness by the one-boson-exchange model, where the $S\text{\ensuremath{-}}D$ wave mixing effect and the coupled channel effect are taken into account in our calculation. Our results suggest that the ${\mathrm{\ensuremath{\Omega}}}_{c}{\overline{D}}_{s}^{*}$ state with ${J}^{P}=3/{2}^{\ensuremath{-}}$ and the ${\mathrm{\ensuremath{\Omega}}}_{c}^{*}{\overline{D}}_{s}^{*}$ state with ${J}^{P}=5/{2}^{\ensuremath{-}}$ can be recommended as the candidates of the hidden-charm molecular pentaquark with triple strangeness. Furthermore, we discuss the two-body hidden-charm strong decay behaviors of these possible hidden-charm molecular pentaquarks with triple strangeness by adopting the quark-interchange model. These predictions are expected to be tested at the LHCb, which can be a potential research issue with more accumulated experimental data in near future.
