Description
In this work, we show our recent theoretical results for three-body systems in the charm sector which are made of three hadrons and contain one nucleon, one D meson and in addition another meson, Dbar, K or Kbar. The Fixed Center Approximation to the Faddeev equations was used, in which we take a cluster of two particles and allow the third one to interact with either of the constituents of the cluster. The cluster wave function as well as the interaction of its components with the the third particle are obtained using two body interaction amplitudes from the chiral unitary approach. In all cases, NDDbar, KDN and KbarDN system, we find a three body bound state with hidden charm and open charm respectively. The states have J^P=1/2^+ and massed around 4400 MeV, 3080 MeV and 3150 MeV respectively. The widths are very small for the first two cases (less than 10 MeV) and about 50 MeV for the last state.
