Abstract

Decays of beauty baryons to the D0ph- and Λc+h- final states (where h indicates a pion or a kaon) are studied using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb-1, collected by the LHCb detector. The Cabibbo-suppressed decays Λb0→D0pK- and Λb0→Λc+K- are observed, and their branching fractions are measured with respect to the decays Λb0→D0pπ- and Λb0→Λc+π-. In addition, the first observation is reported of the decay of the neutral beauty-strange baryon Ξb0 to the D0pK- final state, and a measurement of the Ξb0 mass is performed. Evidence of the Ξb0→Λc+K- decay is also reported. © 2014 CERN, for the LHCb Collaboration.
