  "abstract": "Following the work of Capstick and Isgur [\\href{https://doi.org/10.1103/PhysRevD.34.2809}{Phys.~Rev.~D~34,~2809~(1986)}], we systematically study the mass spectrum of the heavy baryons in the relativized quark potential model with chromodynamics. Besides the original Godfrey-Isgur (GI) model, we also adopt a modified GI model which replaces the linear confinement by a screened one. The two models give similar results in our work. All heavy baryons observed so far can be explained as three-quark states. In particular, we identify the $\\Omega_{c}(3000)$/$\\Omega_{b}(6316)$, $\\Omega_{c}(3050)$/$\\Omega_{b}(6330)$, $\\Omega_{c}(3065)$/$\\Omega_{b}(6340)$ and $\\Omega_{c}(3090)$/$\\Omega_{b}(6350)$ states as the $p_{\\lambda}$ excitations with quantum numbers $1/2^{-}$, $3/2^{-}$, $3/2^{-}$ and $5/2^{-}$. The $\\Omega_{c}(3120)$ is a $3/2^{-}$ state with the $p_{\\rho}$ excitation, whose bottom partner is predicted to be $\\Omega_{b}(6446/6457,3/2^{-})$. The higher state $\\Omega_{c}(3188)$ is the $2s_{\\lambda}$ excitation with quantum numbers $1/2^{+}$, and $\\Omega_{c}(3327)$ is a $d_{\\lambda}$ excitation with quantum numbers $3/2^{+}$ or $5/2^{+}$. In addition, the $\\Lambda_{c}(2940)$ with quantum numbers $J^{P}=3/2^{-}$ could be explained as the $p_{\\rho}$ excitation.",
