In the present work, we investigate the decays of with the final state interaction based on the chiral unitary approach. In the final state interaction of the
with its coupled channels, we study the effects of the
channel in the two-body interaction for the reproduction of the
state, where its contribution to the
state can be ignored. Our results for the
invariant mass distributions of the decay
describe the experimental data up to 1 GeV well, with the resonance contributions from the
and
. For the predicted invariant mass distributions of the
decay, we find that the contributions from the
are significant, but not from the
state. With some experimental branching ratios to determine the production vertex factors, we make predictions for the branching ratios of the other decay channels, including the vector mesons, in the
decays, some of which are consistent with the experimental measurements within the uncertainties.
