The Λc(2860), Λc(2880), Ξc(3055) and Ξc(3080) as D-wave baryon states in QCD
In this article, we tentatively assign the Λc(2860), Λc(2880), Ξc(3055) and Ξc(3080) to be the D-wave baryon states with the spin-parity JP=32+, 52+, 32+ and 52+, respectively, and study their masses and pole residues with the QCD sum rules in a systematic way by constructing three-types interpolati...

In this article, we tentatively assign the Λc(2860), Λc(2880), Ξc(3055) and Ξc(3080) to be the D-wave baryon states with the spin-parity JP=32+, 52+, 32+ and 52+, 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 (Lρ,Lλ)=(0,2), (2,0) and (1,1), respectively. The present predictions favor assigning the Λc(2860), Λc(2880), Ξc(3055) and Ξc(3080) to be the D-wave baryon states with the quantum numbers (Lρ,Lλ)=(0,2) and JP=32+, 52+, 32+ and 52+, respectively. While the predictions for the masses of the (Lρ,Lλ)=(2,0) and (1,1) D-wave Λc and Ξc states can be confronted to the experimental data in the future. |
