| contents | We present a study of the $Ω(2380)$ resonance and show that it is consistent with a dynamically generated state arising from the $\bar{K}^*Ξ^*$, $ωΩ$, and $ϕΩ$ interactions. In this picture, the $Ω(2380)$ is analogous to the $Ω(2012)$, which is generated from the $\bar{K}Ξ^*$ and $ηΩ$ channels. The resulting mass, total width, and partial decay widths into the $\bar{K}Ξ^*$ and $\bar{K}^*Ξ$ channels are compatible with the available experimental data. We also discuss possible experimental observables that could provide further insight into the nature of this state. |
