Abstract

We study the K\ensuremathΛ(1405) configuration of the K\mathrmK\ifmmode \else \=\fiN system by considering K\ensuremathπ\ensuremathΣ 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^\ensuremathπ=1/2⁺ predicted in a single-channel potential model and also found in a Faddeev calculation as an a₀(980)N state, with the a₀(980) generated in the K\mathrmK\ifmmode \else \=\fi, \ensuremathπ\ensuremathη interaction.
