摘要: To describe A(1405) as a resonance in baryon-meson scattering, we have investigated the q 3 -qq scattering system with flavor-singlet (0s) 2 (0 p) state (the A 1 pole). The is treated by quark cluster model (QCM). pole bound embedded continuum. We found that peak appears below NK threshold spin-1 2, isospin-0 channel even if mass of above threshold. This disappears when coupling to A' switched off. Using observed hadron kinetic part QCM also be important reproducing just
