Abstract

We study three-body systems composed of D()D^{(*)}, B()B^{(*)} and Bˉ()\bar{B}^{(*)} in order to look for possible bound states or resonances. In order to solve the three-body problem, we use the fixed center approach for the Faddeev equations considering that the BBˉ(BBˉ)B^*\bar{B}^*(B\bar{B}) are clusterized systems, generated dynamically, which interact with a third particle D(D)D(D^*) whose mass is much smaller than the two-body bound states forming the cluster. In the DBBˉDB^*\bar{B}^*, DBBˉD^*B^*\bar{B}^*, DBBˉDB\bar{B} and DBBˉD^*B\bar{B} systems with I=1/2I=1/2, we found clear bound state peaks with binding energies typically a few tens MeV and more uncertain broad resonant states about ten MeV above the threshold with widths of a few tens MeV.
