Hunting for the hidden-charm molecular states with strange quark in $B$ and $B_s$ decays

Qi Wu, Yan-Ke Chen, Gang Li +2

In the present work, we investigate the productions of the molecular states composed of $D_s^{(\ast )}{\bar{D}}^{(\ast )}$ and $D_s^{(\ast )}{\bar{D}}_s^{(\ast )}$ in the $B$ and $B_s$ decays by usi…
