摘要：
We study the K Lambda (1405) configuration of the K (K) over barN system by considering K pi Sigma as a coupled channel. We solve the Faddeev equations for these systems and find confirmation of the existence of a new N* resonance around 1920 MeV, with J(pi) = 1/2(+) predicted in a single-channel potential model and also found in a Faddeev calculation as an a(0)(980) N state, with the a0(980) generated in the K (K) over bar, pi eta interaction.
