Abstract

By an unquenched quark model, we predict a charmed-strange baryon state, namely, the ${\mathrm{\ensuremath{\Omega}}}_{c0}^{d}(1P,1/{2}^{\ensuremath{-}})$. Its mass is predicted to be 2945 MeV, which is below the ${\mathrm{\ensuremath{\Xi}}}_{c}\overline{K}$ threshold due to the nontrivial coupled-channel effect. So the ${\mathrm{\ensuremath{\Omega}}}_{c0}^{d}(1P,1/{2}^{\ensuremath{-}})$ state could be regarded as the analog of the charmed-strange meson ${D}_{s0}^{*}(2317)$. It is a good opportunity for the running Belle II experiment to search for this state in the ${\mathrm{\ensuremath{\Omega}}}_{c}^{(*)}\ensuremath{\gamma}$ mass spectrum experiment in the future.
