Description
Hadrons, including mesons and baryons, constitute the smallest observable units with internal structure that can be separated from matter. The search for new hadronic states and the exploration of the internal quark-gluon structure of hadrons represent a shared frontier research topic in both particle physics and medium-to-high energy nuclear physics. In recent years, an increasing number of exotic hadronic states that lie beyond the predictions of the classical quark model have been experimentally observed. Although various interpretations exist regarding their nature, these exotic states can largely be explained within the framework of the multiquark hadronic molecular state picture. Furthermore, even for hadrons previously thought to conform to the quark model, such as the proton, new experimental observables have emerged that cannot be explained by the classical quark model and require the consideration of multiquark components arising from unquenching mechanisms. Consequently, a true understanding of the hadron spectrum and hadron structure necessitates the study of multiquark exotic hadronic states.
