Study of possible $DN{D}^{\ast }$ bound states

Victor Montesinos, Jing Song, Wei-Hong Liang +3

We start from a recently favored picture in which the $\hat{I}{›}_c(2940)$ and $\hat{I}{›}_c(2910)$ correspond mostly to $N{D}^{\ast }$ bound states with $J^P=1/2^{-},3/2^{-}$ and then add a $D$ as a thi…
