Abstract

A large dataset collected by the LHCb experiment in proton-proton collisions during Runs 1 and 2 of the Large Hadron Collider has opened a unique possibility to study beauty baryons and to broaden knowledge of their spectroscopy. Recent results on searches for new Λ0 b baryon decays are reviewed. In particular, the observation of two new Λ0 b → ψ(2S)pπ− and Λ0 b → χc1pπ− decays and the evidence for the Λ0 b → χc2pπ− decay are presented. Measurements of their branching fractions relative to that of the control channels are described.
