Revisiting the Ω(2012) as a hadronic molecule and its strong decays

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.
