Description
Recently, the study of the exotic hadron is of current interest in the Nuclear and Hadron physics. In particular, the charged quarkonia, such as Zc(3900), having the genuinely exotic structure attract a lot of interest. The exotic states near the hadron-hadron threshold have been considered to be a hadronic molecule, while the hadron-hadron interaction is not established yet in the heavy flavor sectors. In this study, we focus on the interaction in the pi J/psi-DDbar* coupled-channel. The short-range interaction is described by the quark exchange diagram. We also find the difference between the results of the meson exchange picture and the quark exchange one.
