Description
We study the compositeness of near-threshold states to clarify the internal structure of exotic hadron candidates. Within the framework of effective field theory, we extend the Weinberg's weak-binding relation to include the nearby CDD (Castillejo-Dalitz-Dyson) pole contribution with the help of the Padé approximant. Finally, using the extended relation, we conclude that the CDD pole contribution to the Λ(1405) baryon in the K-barN amplitude is negligible. (author)
