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 ${\Lambda }_c(2940)$ and ${\Lambda }_c(2910)$ correspond mostly to $N{D}^{\ast }$ bound states with $J^P=1/2^{-},3/2^{-}$ and then add a $D$ as a third…
