英文摘要	The chiral dynamics of the doubly heavy baryons is solely governed by the light quark. In this paper, we have derived the chiral corrections to the mass of the doubly heavy baryons up to (NLO)-L-3. The mass splitting of Xi(cc) and Omega(cc) at the (NLO)-L-2 depends on one unknown low energy constant c(7). By fitting the lattice masses of Xi(cc)(3520), we estimate the mass of Omega(cc) to be around 3.726 GeV. Moreover, we have also performed a systematical analysis of the chiral corrections to the axial currents and axial charges of the doubly heavy baryons. The chiral structure and analytical expressions will be very useful to the chiral extrapolations of the future lattice QCD simulations of the doubly heavy baryons.
