Strong decay modes $\bar{K}\Xi$ and $\bar{K}\Xi \pi$ of the $\Omega (2012)$ in the $\bar{K}\Xi (1530)$ and $\eta \Omega$ molecular scenario

Abstract

We study the $\bar{K}\Xi$ decay mode of the newly observed $\Omega (2012)$ assuming that the $\Omega (2012)$ is a dynamically generated state with spin-parity $J^P=3/2^{-}$ from the coupled channel $S$-wave interactions of $\bar{K}\Xi (1530)$ and $\eta \Omega$. In addition we also calculate its $K\pi \Xi$ three-body decay mode. It is shown that the so-obtained total decay width is in fair agreement with the experimental data. We compare our results with those of other recent studies and highlight differences among them.
