Abstract

We study the KΛ(1405)K\Lambda(1405) configuration of the KKˉNK\bar{K}N system by considering KπΣK\pi\Sigma as a coupled channel. We solve the Faddeev equations for these systems and find confirmation of the existence of a new NN^{*} resonance around 1920 MeV with Jπ=1/2+J^{\pi}=1/2^{+} predicted in a single-channel potential model and also found in a Faddeev calculation as an a0(980)Na_{0}(980)N state, with the a0(980)a_{0}(980) generated in the KKˉK\bar{K}, πη\pi\eta interaction.
