报告简介：

Compositeness is an important concept to promote a quantitative understanding of the inner structure for a molecular state. We introduce the compositeness formalism for the case of the resonance, as a generalization of bound-state case. We have also proposed a more general form of two-body scattering amplitude with explicit inclusion of CDD pole, which is more widely applicable than the effective range expansion. Combining those with the experimental input, we get some interesting conclusions that are not found in the previous literature.
