摘要：

In this article, we tentatively assign the Lambda(c)(2860), Lambda(c)(2880), Xi(c)(3055) and Xi(c)(3080) to be the D-wave baryon states with the spin-parity J(P) = 3/2(+), 5/2(+), 3/2(+) and 5/2(+), respectively, and study their masses and pole residues with the QCD sum rules in a systematic way by constructing three-types interpolating currents with the quantum numbers (L-rho, L-lambda) =(0, 2), (2, 0) and (1, 1), respectively. The present predictions favor assigning the Lambda(c)(2860), Lambda(c)(2880), Xi(c)(3055) and Xi(c)(3080) to be the D-wave baryon states with the quantum numbers (L-rho, L-lambda) =(0, 2) and J(P) = 3/2(+), 5/2(+), 3/2(+) and 5/2(+), respectively. While the predictions for the masses of the (L-rho, L-lambda) =(2, 0) and (1, 1) D-wave Lambda(c) and Xi(c) states can be confronted to the experimental data in the future. (C) 2017 The Author.
