N2 - We extend the study of a JP=2+,I=3/2, πΛN quasibound state by solving nonrelativistic Faddeev equations, using 3S1-3D1, ΛN-ΣN coupled channels chiral quark model local interactions, and πN and coupled πΛ-πΣ separable interactions fitted to the position and decay parameters of the Δ(1232) and Σ(1385) resonances, respectively. The results exhibit a strong sensitivity to the p-wave pion-hyperon interaction, with a πΛN quasibound state persisting over a wide range of acceptable parametrizations.
