Two-body strong decays of the hidden-charm tetraquark molecular states via the QCD sum rules

Tao Hong, Xiao-Song Yang, Zhi-Gang Wang

In this work, we extend our previous work on the $D^{\ast }{\bar{D}}^{\ast }$ molecular states with the $J^{PC}=0^{++}$, $1^{+-}$ and $2^{++}$ to investigate their two-body strong decays via the…
