Description

Hadrons that are difficult to explain as ordinary hadrons are called exotic hadrons, and since the Belle experiment reported $X(3872)$ in 2003, a large number of exotic hadrons containing charm quarks have been reported. Some of these have the same quantum number as charmonium and are located near the mass threshold of the two hadrons. In this study, we analyze the exotic hadrons associated with $\chi_{cJ}(2P)$ as superpositions of bare $\chi_{cJ}(2P)$ and $D^{(*)}\bar{D}^{(*)}$ hadronic molecules.
