Abstract

We introduce two basic concepts: the compositeness for resonance and the Castillejo-Dalitz-Dyson (CDD) pole. Applying them to hadron states X(3872)X(3872), Zb(10610)Z_b(10610) and Zb(10650)Z_b(10650), and TccT_{cc}, we obtain their compositeness values and achieve deeper insights into their inner structure.
