Investigation of the $X(4020)$ peak in the $D^{\ast }{\bar{D}}^{\ast }$ and $\pi h_c$ channels

Shuntaro Sakai

In this paper, the nature of $X(4020)$ observed in the vicinity of the $D^{\ast }{\bar{D}}^{\ast }$ threshold of the $\pi h_c$ and $D^{\ast }{\bar{D}}^{\ast }$ distributions is studied. Using a model containing on…
