We discuss selected and important features of hadronic molecules as one of promising forms of exotic hadrons near thresholds. Using examples of $D \bar D^*$ systems such as $X(3872)$ and $Z_c$, emphasis is put on the roles of the one pion exchange interaction between them and their coupling to intrinsic quark states. Thus hadronic molecules emerge as admixtures of the dominant long-range hadron structure and short-range quark structure. For the pion exchange interaction, properties of the… Expand

Classifying Near-Threshold Enhancement Using Deep Neural Network
One of the main issues in hadron spectroscopy is to identify the origin of threshold or near-threshold enhancement. Prior to our study, there is no straightforward way of distinguishing even theExpand

We study exotic mesons with double charm and bottom flavor, whose quark configuration is \bar{Q}\bar{Q}qq. This quark configuration has no annihilation process of quark and antiquark, and hence is aExpand
Light quark mass dependence of the X(3872) in an effective field theory

Study of X(3872) from effective field theory with pion-exchange interaction.
This calculation provides a theoretical confirmation of the existence of the 1++ state X(3872), and the light quark mass dependence of the pole position indicates it has a predominately DD[ over ¯]* (D*D[over ¯]) molecular nature. Expand
