摘要：

The I > (c) (2940)(+) is studied in a constituent quark model. The model describes the deuteron as an NN bound state and the X(3872) as a DD* molecule. We studied the meson baryon sector and found a D*N bound state consistent with the data available for the I > (c) (2940)(+). The existence of this bound state in this picture implies the existence of a partner that we predict as a I > (b) (6248). Different decay channels for this state are also studied.
