Three-body systems with open flavor heavy mesons

We solve the Faddeev equations for the bound state problem of three particles to study different three-body systems containing open flavor heavy mesons: DNN, BNN, DDN and BBN. We use a coupled-channel formalism considering the S-wave spin excitations of the constituent hadrons: D∗, B∗, and Δ when deemed relevant. Our study comes motivated by the recent prediction of deeply bound states in different two-body subsystems participating in the aforementioned three-body states. The existence of three-body bound states with open flavor heavy mesons would open the door to exotic nuclei with heavy flavors. Our results point against such possibility.
