Hadronic Molecules and $I ¨ _{c J} (2 P)$ Coupled States

Kotaro Miyake, Yasuhiro Yamaguchi

We investigate hidden-charm exotic mesons based on a coupled-channel framework, where the physical states are described as superpositions of a compact $c c ˉ$ core (identified wi…

Hidden-Charm Tetraquarks in a Mixture Model: Coupled-Channel Analysis with $c c ˉ$ and Hadronic Molecular Components

Kotaro Miyake, Yasuhiro Yamaguchi

The nature of the $X (3872)$ and other exotic hadrons has been a subject of extensive investigation since the first observation of the $X (3872)$ in 2003. While various theoretical m…
