Such an interaction is, however, realized by pion-charmed baryon system $\\pi \\Sigma_c$, which has a narrow resonance $\\Lambda_c^+(2595)$ located a few MeVs above its threshold. We study the consequence of narrowly resonant inter-species interaction in a three-body system composed of two identical light bosons and an extremely heavy particle. We concern ourselves in the present paper with resonances of the three-body system, as opposed to bound states.
