Abstract
Recently,a new excited baryon state,Ω(2012),was observed in the invariant mass spectra of K-Ξ0 and K0SΞ-by the Belle collaboration.This state has a narrow width(～6MeV)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 KΞ(1530)and ηΩ in s-wave and KΞ in d-wave.Additionally,alternative explanations for the Ω(2012)resonance are also discussed.
