The $1D$, $2D$ $\Xi_{b}$ and $\Lambda_{b}$ baryons
Abstract
Recently, scientists have made great progresses in experiments in searching for the excited states of and baryons such as the , , , , , and . Stimulated by these progresses, we give a systematical analysis about the and states of and baryons with the method of QCD sum rules. By constructing three types of interpolating currents, we calculate the masses and pole residues of these heavy baryons with different excitation modes , and . As a result, we decode the inner structures of , , and , and favor assigning these states as the baryons with the quantum numbers and , , and , respectively. In addition, the predictions about the masses and pole residues of the other and states of and baryons in this paper are helpful in studying the D-wave bottom baryons in experiments in the future.
