Description
The dynamical nature of the exotic baryons, for example N(1535) and Lambda(1405) remain elusive. In this talk, I will talk about the poles dynamical generated by the meson-baryon interaction up to NLO. By extrapolating the poles with different quantum sectors (S, I) = (-1, 0), (0, 1/2), (-2, 1/2) from the physical quark mass setting to su3 limit (mpi=700 MeV), we can reveal the relations between the multiplet and the poles, and also the compositeness of the quark contents, for example ssbar content in the exotic baryons.
