Query: Strong decays of the hadronic molecule $\Omega^\ast (2012)$   Strong two- and three-body decays of the new excited hyperon $\Omega^*(2012)$
are discussed in the hadronic molecular approach. The $\Omega^*(2012)$ state is
considered to contain the mixed $\Xi \bar K$ and $\Omega \eta$ hadronic
components. In our calculations we use a phenomenological hadronic Lagrangian
describing the coupling of the bound states to its constituents and of the
constituents to other hadrons occurring in the final state. Our results show
that the decay widths of the two-body decay modes $\Omega^*(2012) \to \Xi \bar
K$ lie in the few MeV region and are compatible with or dominate over the rates
of the three-body modes $\Omega^*(2012) \to \Xi \pi \bar K$. The sum of two-
and three-body decay widths is consistent with a width of the $\Omega^*(2012)$
originally measured by the Belle Collaboration. A possible scenario for the
suppression of the three-body decay rate recently noticed by the Belle
Collaboration is due to the dominant admixture of the $\Omega \eta$ hadronic
component in the $\Omega^*(2012)$ state.
