摘要：
In the framework of Regge phenomenology, the masses of the charmed states cq̄ (q=u,d,s) lying on the 13S1-like trajectories are estimated. The overall agreement between our estimated masses and the recent predictions given using modified quark models by Matsuki et al., Lakhina et al. and Close et al. is good. The masses of the observed charmed states Ds0(2317), DsJ(2860) and DsJ(2690)/DsJ(2700) can reasonably be reproduced in the picture of these charmed states as simple quark–antiquark configurations. We therefore suggest that Ds0(2317) can be identified with the cs̄(13P0) states. The possible assignments of the DsJ(2860) and DsJ(2690)/DsJ(2700) are discussed.
