Revisiting the $\mathrm{\Omega }(2012)$ as a hadronic molecule and its strong decays

Recently, the Belle collaboration measured the ratios of the branching fractions of the newly observed $\mathrm{\Omega }(2012)$ excited state. They did not observe significant signals for the $\Omega(2012) \to \bar{K} \Xi^(1530) \to \bar{K} \pi \Xi$ decay, and reported an upper limit for the ratio of the three body decay to the two body decay mode of $\mathrm{\Omega }(2012)\to \bar{K}\mathrm{\Xi }$. In this work, we revisit the newly observed $\mathrm{\Omega }(2012)$ from the molecular perspective where this resonance appears to be a dynamically generated state with spin-parity $3\mathrm{/}{2}^{-}$ from the coupled channels interactions of the $\bar{K} \Xi^(1530)$and$\eta \Omega$in$s$-waveand$\bar{K} \Xi$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.
