In this study, we analyzed the weak decays induced by [Formula presented] transitions within the light-cone sum rules. Specifically, semileptonic decays of the bottom baryons into the P-wave baryons Λb→Λc(2625)ℓνl and Ξb→Ξc(2815)ℓνl as well as nonleptonic Λb→Λc(2625)π(ρ) and Ξb→Ξc(2815)π(ρ) decays are investigated. The form factors for the considered transitions are obtained within the sum rules method. With the calculated form factors, the decay widths of the processes are determined. Up to now, only the decay width for Λb0→Λc+μ−νμ has been measured among the considered decays, and we observe that our finding is quite compatible with the measurement. We also compare our results with the predictions of other approaches.
