We study the BββKβΞ·Ξ·cβ decay by taking into account the
S-wave contributions from the pseudoscalar meson--pseudoscalar meson
interactions within the unitary coupled-channel approach, where the DDΛ
bound state is dynamically generated. In addition, the contribution from the
intermediate resonance K0ββ(1430), with K0ββ(1430)βKβΞ·, is also
considered. Our results show that there is a clear peak around 3730~MeV in
the Ξ·Ξ·cβ invariant mass distribution, which could be associated with
the DDΛ bound state. The future precise measurements of the BββKβΞ·Ξ·cβ process at the Belle II and LHCb experiments could be,
therefore, used to check the existence of the DDΛ bound state, and to
deepen our understanding of the hadron-hadron interactions.Comment: 8 pages, 8 figure
