英文摘要	Recently, the Belle collaboration measured the ratios of the branching fractions of the newly observed Omega(2012) excited state. They did not observe significant signals for the Omega(2012)-> K Xi(1530)-> K pi Xi decay, and reported an upper limit for the ratio of the three body decay to the two body decay mode of Omega(2012)-> K Xi. In this work, we revisit the newly observed Omega(2012) from the molecular perspective where this resonance appears to be a dynamically generated state with spin-parity 3/2- from the coupled channels interactions of the K Xi(1530) and eta Omega in s-wave and K Xi in d-wave. With the model parameters for the d-wave interaction, we show that the ratio of these decay fractions reported recently by the Belle collaboration can be easily accommodated.
