Constraining the $DD{D}^{\ast }$ three-body bound state via the $Z_c(3900)$ pole

Hai-Xiang Zhu, Lu Meng, Yao Ma +3

In this study, we propose using the $Z_c(3900)$ pole position to constrain the existence of the $DD{D}^{\ast }$ three-body bound state within the one-boson-exchange (OBE) model. The existe…
