The Ω(2012) as a Hadronic Molecule
Abstract
Recently, a new excited baryon state, Ω(2012), was observed in the invariant mass spectra of and by the Belle collaboration. This state has a narrow width (∼ 6 MeV) compared to other baryon states with a similar mass. Here, we provide a mini-review on the Ω(2012) state from the molecular perspective, where it appears to be a dynamically generated state with spin-parity 3/2- from the coupled-channels interactions of the and ηΩ in s-wave and in d-wave. Additionally, alternative explanations for the Ω(2012) resonance are also discussed.
