【 摘 要 】

Recent measurements of b-baryon decays using 3fb-1proton-proton collision data collected by the LHCb experiment are presented. Measurements of the branching fractions of Λ0b→ J/ψpπ-, Λ0b→ Λ+cD-s, Λ0b→ Λ+cD-and Λ0b→ Λ+cπ-decays have been made, as well as precise measurements of the mass and lifetime of the Ξ0bHb baryon. In addition, the pTand η dependence of the ratio of Λ0bto B0production fractions has been measured.
