摘要：
Recently, a new excited baryon state, Omega(2012), was observed in the invariant mass spectra of K-Xi(0) and K-S(0)Xi- by the Belle collaboration. This state has a narrow width (similar to 6 MeV) compared to other baryon states with a similar mass. Here, we provide a mini-review on the Omega(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 K<overline>Xi(1530) and eta Omega in s-wave and K<overline>Xi in d-wave. Additionally, alternative explanations for the Omega(2012) resonance are also discussed.
