Abstract
We present recent progress in the study of the origin of baryon resonances in chiral dynamics. It is shown that in the chiral coupled-channel approach, the form of the interaction cannot be specified due to the cutoff of the loop integral. To avoid this ambiguity, we propose a natural renormalization scheme, which affords a clue to the origin of the resonance, together with the phenomenological fitting to experimental data. We study the structure of the Λ(1405) resonance in comparison with the N(1535).
