The Cabibbo-suppressed decays Λ 0 b → D 0 p K − and Λ 0 b → Λ + c K − are observed, and their branching fractions are measured with respect to the decays Λ 0 b → D 0 p π − and Λ 0 b → Λ + c π − . In addition, the first observation is reported of the decay of the neutral beauty-strange baryon Ξ 0 b to the D 0 p K − final state, and a measurement of the Ξ 0 b mass is performed. Evidence of the Ξ 0 b → Λ + c K − decay is also reported.15 p.application/pdfengcc by (c) CERN; LHCb Collaboration, 2014http://creativecommons.org/licenses/by/3.0/es/Física de partículesGran Col·lisionador d'HadronsBarionsParticle physicsLarge Hadron Collider (France and Switzerland)Baryonsinfo:eu-repo/semantics/article6457372019-04-02info:eu-repo/semantics/openAccess
