Predicting a new resonance as charmed-strange baryonic analog of $D_{s0}^{\ast }(2317)$

Abstract

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