Exotic Hadrons and Candidates

Anatomy of the internal structures of the exotic hadrons in a quantitative manner


  • Prof. Zhi-Hui GUO

Primary authors



We apply the effective range expansion and generalized Weinberg's compositeness relations to analyze the internal structures of several exotic hadron candidates near underlying two-body thresholds. This formalism enables us to give quantitative estimates of the weights of different constituents inside the exotic hadrons. Useful information, including the partial decay widths, can be predicted, which may provide meaningful guide for future experimental measurements.
