| contents | We present the explicit form of the Regge trajectory relations for the triply heavy bottom-charm baryons, which can be applied to investigate both the $λ$-mode excited states and the $ρ$-mode excited states. We estimate the masses of the $λ$-excited states and the $ρ$-excited states. The results are in agreement with other theoretical predictions. Both the $λ$-trajectories and the $ρ$-trajectories are discussed. Moreover, the behaviors of the $λ$- and $ρ$-trajectories for various baryons are discussed. It is shown that both the $λ$-trajectories and the $ρ$-trajectories for baryons are concave downwards in the $(M^2,\,x)$ plane. The Regge trajectories for the light baryons are approximately linear and become concave as the masses of the light constituents are considered. |
