Recently, the Belle and LHCb Collaborations have measured the decay and reported the
invariant mass distribution, which shows a clear cusp structure around the
threshold. In this work, we have analyzed this process by considering the triangle mechanism and the S-wave pseudoscalar meson-octet baryon interactions within the chiral unitary approach, which dynamically generates the
. Our results are in good agreement with the Belle measurements, which implies that the cusp structure around
threshold could be associated with the
with the molecular nature.
