Abstract

The newly observed ${\mathrm{\ensuremath{\Omega}}}_{c}(3327)$ gives us a good chance to construct the ${\mathrm{\ensuremath{\Omega}}}_{c}$ charmed baryon family. In this work, we carry out the mass spectrum analysis by a nonrelativistic potential model using the Gaussian expansion method, and the study of its two-body Okubo-Zweig-Iizuka--allowed strong decay behavior. Our results imply that the ${\mathrm{\ensuremath{\Omega}}}_{c}(3327)$ is a good candidate of the ${\mathrm{\ensuremath{\Omega}}}_{c}(1D)$ state with ${J}^{P}=5/{2}^{+}$. We also predict the spectroscopy behavior of other ${\mathrm{\ensuremath{\Omega}}}_{c}(1D)$ states, which may provide further clues to their search.
