Abstract

We suggest some possible interpretations for the DSJ+(2632)D_{SJ}^+(2632) observed by SELEX. The DSJ+(2632)D_{SJ}^+(2632) could be the first radial excitation of the 11^- ground state Ds\rm{D_s}^*(2112), and its unusual decay patten might be hopefully explained by the node structure of the wave functions. In addition, the DSJ+(2632)D_{SJ}^+(2632) could also be a csˉgc\bar sg hybrid state or a (cs)3(sˉsˉ)3(cs)_{3^*}-(\bar s\bar s)_{3} (diquark-antidiquark) bound state.
