Abstract

We have studied the ND*K¯* system in the framework of the fixed center approximation to the Faddeev equations, taking the exotic D*K¯* system as the cluster and allowing the N to interact with the components of the cluster. Previous studies have determined the existence of three states of spin 0, 1, 2 for the D*K¯* system, the one of spin 0 associated to the X0(2900) state observed by the LHCb Collaboration. From this perspective, we find five states with total spin 1/2,3/2,5/2, with bindings from 10 to 30 MeV and widths below 60 MeV, which could be well identified. We also discuss the decay channels of these states that should help in future experimental searches for these states.
