Strong decay modes bar{K}Xi and bar{K}Xiπ of the Ω(2012) in the bar{K}Xi(1530) and ηΩ molecular scenario
read the original 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.

Probing the hadronic molecular nature of the $\Omega(2012)$, $\Omega(2380)$, and $\Omega_c(3120)$ via femtoscopy correlation functions
Correlation function calculations with coupled-channel potentials produce low-momentum enhancements that the authors interpret as signatures of the molecular structure of Ω(2012), Ω(2380), and Ωc(3120).

Probing the hadronic molecular nature of the $\Omega(2012)$, $\Omega(2380)$, and $\Omega_c(3120)$ via femtoscopy correlation functions
Numerical correlation functions computed from effective potentials exhibit enhancements that indicate the hadronic molecular nature of the Ω(2012), Ω(2380), and Ωc(3120) resonances.
