摘　　要：We study the masses of the doubly bottom baryons and the charmed-bottom baryons up to O(p^(3))in heavy baryon chiral perturbation theory.We determine the unknown low energy constants in the quark model and lattice QCD.We show the numerical results for the masses of the doubly bottom baryons and the charmed-bottom baryons up to O(p^(3)).
