| contents | Mass spectra and decay properties of the low-lying orbital excited $Ξ_c^{(\prime)}$ baryons are investigated in the framework of the chiral quark model and quark pair creation mechanism, which are mainly based on the recently experimental fact that $Ξ_c(3055)$ is a $D$-wave state excited in $λ$-mode. As a result, we make an inference that, (i) $Ξ_{c}(2790)$ and $Ξ_{c}(2815)$ are likely to be $λ$-mode excited $Ξ_{c1}(\frac{1}{2}^{-},1P)$ and $Ξ_{c1}(\frac{3}{2}^{-},1P)$ states, respectively. (ii) $Ξ_{c}(2923)$ and $Ξ_{c}(2939)$ could correspond respectively to the $Ξ_{c1}^{\prime}({\frac{1}{2}^{-}},1P)$ and $Ξ_{c2}^{\prime}({\frac{5}{2}^{-}},1P)$ states, while $Ξ_{c}(2965)$ might be a $ρ$-mode excited $Ξ_{c0}(\frac{1}{2}^{1},1P)$ state, and $Ξ_{c}(2882)$ might be arranged as $Ξ_{c0}^{\prime}(\frac{1}{2}^{-},1P)$. (iii) $Ξ_{c}(2970)$ might be the $Ξ_{c}(\frac{1}{2}^{+},2S)$ state. (iv) $Ξ_{c}(3055)$ and $Ξ_{c}(3080)$ can form a $λ$-mode excited $D$-wave doublet $Ξ_{c2}(\frac{3}{2}^+,\frac{5}{2}^+)$. |
