Abstract
We evaluate the partial decay widths for the semileptonic and decays from the perspective that these two resonances are dynamically generated from the and interaction with coupled channels. We find that the ratio of the rates obtained for these two reactions is compatible with present experimental data and is very sensitive to the coupling, which becomes essential to obtain agreement with experiment. Together with the results obtained for the reactions, it gives strong support to the molecular picture of the two resonances and the important role of the component neglected in prior studies of the from the molecular perspective.
