| Outline of Final Research Achievements |
In this study, with the analysis of chiral effective theories, the novel structure of the Lambda(1405) in the antikaon-nucleon systems is clarified. The main results are (1) the establishment of the hadron molecule structure of Lambda(1405) and the construction of the realistic Kbar N interaction, (2) the generalization of the method to determine the hadron compositeness to unstable states, and (3) the extension to the heavy quark systems. It is shown that the hadron molecule structures ubiquitously emerge in a wide range of fields including the strangeness systems, and the technique to experimentally determine the internal structure in a model-independent manner is developed.
