Abstract
The pseudoscalar meson-baryon octet interaction is studied within a nonlinear realized Lagrangian, and then the Bethe-Salpeter equation is solved in the unitary coupled-channel approximation. In sector of strangeness and isospin , only one pole is generated dynamically in the 1400MeV region, which might correspond to the particle. When the case of strangeness zero is studied, the and potentials are taken into account in the kernel, and a resonance state is produced in the 1500MeV region, which might be a counterpart of the N(1535) particle.
