Abstract

We have studied the NDKˉN D^* \bar{K}^* system in the framework of the Fixed Center Approximation to the Faddeev equations, taking the exotic DKˉD^* \bar{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 0,1,20,1,2 for the DKˉD^* \bar{K}^* system, the one of spin 00 associated to the X0(2900)X_0(2900) state observed by the LHCb collaboration. From this perspective, we find five states with total spin 1/2,3/2,5/21/2,3/2,5/2, with bindings from 1010 to 3030 MeV and widths below 6060 MeV, which could be well identified. We also discuss the decay channels of these states that should help in future experimental searches of these states.
