Decay behaviors of possible ${\Lambda }_{c\bar{c}}$ states in hadronic molecule pictures

Chao-Wei Shen, Jia-Jun Wu, Bing-Song Zou

In 2010, ${\Lambda }_{c\bar{c}}^{\ast }$ states were predicted as the strange number $S=-1$ partners of $N_{c\bar{c}}^{\ast }$, which are well known now as the $P_c$ states and observed experimentally…
