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

28 Jun 2020 Lu Jun-Xu Zeng Chun-Hua Wang En Xie Ju-Jun Geng Li-Sheng

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 $\Omega(2012) \to \bar{K} \Xi^*(1530) \to \bar{K} \pi \Xi$ decay, and reported an upper limit for the ratio of the three body decay to the two body decay mode of $\Omega(2012) \to \bar{K} \Xi$...
