| dc.description | We propose that the Y(4260) particle recently announced by BaBar is the first orbital excitation of a diquark-antidiquark state ([cs][cbar sbar]). Using parameters recently determined to describe the X(3872) and X(3940) we show that the Y mass is compatible with the orbital excitation picture. A crucial prediction is that Y(4260) should decay predominantly in D_s D_sbar. The Y(4260) should also be seen in B non-leptonic decays in association with one kaon. We consider the full nonet of related four-quark states and their predicted properties. Finally, we comment on a possible narrow resonance in the same channel. | |
