The newly observed ${\Omega }_c(3327)$: A good candidate for a $D$-wave charmed baryon

Abstract

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