摘要：
The s-wave meson-baryon interaction is described using the lowest-order SU(3) chiral Lagrangian in a unitary coupled-channels Bethe-Salpeter equation. The entire octet of ground-state J(P) = 1/2(-) resonances, the Lambda(1670), Sigma(1620), Xi(1620) and N(1535) states, along with the SU(3) singlet Lambda(1405), is found to be dynamically generated through meson-baryon rescattering.
