We study their strong decays assuming they are D-wave states. Some assignments are excluded by comparing our numerical results with the experimental values of the total widths of c（3055）^＋ and c（3123）^＋.

文摘The Babar Collaboration announced two new excited charmed baryons c（3055）^＋ and c（3123）^＋. We study their strong decays assuming they are D-wave states. Some assignments are excluded by comparing our numerical results with the experimental values of the total widths of c（3055）^＋ and c（3123）^＋. We also suggest some possible decay modes, which will be helpful to determine the properties of c（3055）^＋ and c（3123）^＋.
