The $\Omega(2380)$ as a partner of the $\Omega(2012)$

TL;DR

This paper models the $ ext{Ω}(2380)$ resonance as a dynamically generated state from specific meson-baryon interactions, aligning with experimental data and drawing parallels to the $ ext{Ω}(2012)$.

Contribution

It proposes a novel dynamical generation mechanism for the $ ext{Ω}(2380)$ resonance based on meson-baryon interactions, extending the understanding of these states.

Findings

Mass, width, and decay widths match experimental data.

The $ ext{Ω}(2380)$ is similar to the $ ext{Ω}(2012)$, generated from different channels.

Possible experimental observables are discussed for further validation.

Abstract

We present a study of the $\Omega(2380)$ resonance and show that it is consistent with a dynamically generated state arising from the $\bar{K}^*\Xi^*$, $\omega\Omega$, and $\phi\Omega$ interactions. In this picture, the $\Omega(2380)$ is analogous to the $\Omega(2012)$, which is generated from the $\bar{K}\Xi^*$ and $\eta\Omega$ channels. The resulting mass, total width, and partial decay widths into the $\bar{K}\Xi^*$ and $\bar{K}^*\Xi$ 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.
