Coupled-channel study of the three-body $DDK$ and $D^{\ast }{D}^{\ast }K$

Hai-Peng Xie, Si-Yi Chen, Ning Li +1

We investigate the three-body $DDK$ system with quantum numbers $I(J^P)=\frac{1}{2}(0^{-})$ within a coupled-channel framework that incorporates both $DDK$ and $D^{\ast }{D}^{\ast }K$ config…
