英文摘要	We systematically study the S-wave doubly charmed baryons using the method of QCD sum rules. Our results suggest that the Xi(++)(cc) recently observed by LHCb can be well identified as the S-wave Xi(cc) state of J(P) = 1/2(+). We study its relevant Omega(cc) state, the mass of which is predicted to be around 3.7 GeV. We also systematically study the P-wave doubly charmed baryons, the masses of which are predicted to be around 4.1 GeV. Especially, there can be several excited doubly charmed baryons in this energy region, and we suggest searching for them in order to study the fine structure of the strong interaction.
