N2 - We have searched for bound states in the πΛN system by solving the nonrelativistic Faddeev equations, as well as a relativistic version, with input separable πN, πΛ, and ΛN interactions. A bound-state solution, driven by the Δ(1232) and the Σ(1385) p-wave meson-baryon resonances, was found in the channel (I,JP)=(32,2+), provided the Λ laboratory momentum at which the ΛN S13 phase shift becomes negative is larger than plab∼750-800MeV/c. Other strange and charmed πBB′ systems that might have bound states of a similar nature are listed.
