Implication of the Existence of JPC=0 - D ¯ sDK Bound State on the Nature of Ds0∗ (2317), and a New Configuration of Exotic State

The discovery of numerous new hadrons over the past two decades has provided unprecedented opportunities to understand the nonperturbative QCD and hadron structure. The hadronic molecule picture plays an important role in explaining these new hadrons and enriching the configurations of exotic hadronic states. In this Letter, using the model-independent DK potential extracted from the relevant experimental data, a JPC=0 - D¯sDK three-body hadronic molecule is predicted with a mass of 4310-24+14 MeV. This state shows decoupling to conventional cc¯ charmonia or the D¯sDs0∗(2317) two-body molecular state. It can be regarded as a compelling three-body hadronic molecular candidate. We further demonstrate that the B+→D∗±D∓K+ decays could be promising channels for searching for the predicted state in future high-luminosity LHCb runs.
