Abstract

The relativistic chiral Lagrangians for both spin-12\frac{1}{2} and spin-32\frac{3}{2} doubly charmed baryons are constructed up to the order O(p4)\mathcal{O}(p^{4}). From O(p2)\mathcal{O}(p^{2}) to O(p4)\mathcal{O}(p^{4}), there are 19, 74, and 452 independent terms in the two-flavor case and 25, 112, and 864 independent terms in the three-flavor case. The chiral Lagrangians in the heavy diquark limit are also obtained. From O(p2)\mathcal{O}(p^{2}) to O(p4)\mathcal{O}(p^{4}), there are 7, 23, and 118 independent terms in the two-flavor case and 8, 31, and 189 independent terms in the three-flavor case. We present the low-energy constant relations between the relativistic case and the case in the heavy diquark limit up to the order O(p3)\mathcal{O}(p^{3}). With the heavy diquark-antiquark symmetry, the low-energy constant relations between the doubly charmed baryon case and the heavy-light meson case are also obtained up to the order O(p3)\mathcal{O}(p^{3}).
