英文摘要	The measured masses and strong decays of Lambda(b) (6146)(0) and Lambda(b)(6152)(0) required us to decode them as the 1D excited states with J(P) = 3/2(+) and J(P) = 5/2(+), respectively. Under the suggested assignment, the masses and total decay widths of Lambda(b) (6146)(0) and Lambda(b)(6152)(0) can be explained. As a J(P) = 3/2(+) state, the Lambda(b) (6146)(0) should mainly decay into Sigma(b)(5815)(p). However, this theoretical result is in contradiction to the measurement since no significant Sigma(b)(6146)(0) -> Sigma(b)(5815)(+/-)pi(-/+) signals were observed by the LHCb. The possible explanations for this difficulty are mentioned. For completeness, we present the prediction of masses and decay widths of other unseen 1D bottom baryons in this work. Our results could provide some important clues for the upcoming experiments.
