Description
Recent accelerator experiments have reported unexpected states known as exotic hadrons, whose properties cannot be explained by the conventional picture. In the heavy quark sector, $XYZ$, $T_{cc}$, $P_c$ etc. have been reported since the discovery of $X(3872)$. Many exotic hadrons are located near the hadron threshold, and thus hadronic molecular structures have been considered. In this talk, we study hadronic molecules of heavy hadrons. In the heavy hadron sector, the heavy quark symmetry is important, which induces channel coupling effects and also predicts partner states. We study bound state properties of hadronic molecules and also discuss partner states of these exotics, predicted by symmetries.
