Abstract

Decays of beauty baryons to the D⁰ph^- and Λ⁺_ch^- 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 Λ⁰_b→D⁰pK^- and Λ⁰_b→Λ⁺_cK^- are observed, and their branching fractions are measured with respect to the decays Λ⁰_b→D⁰pπ^- and Λ⁰_b→Λ⁺_cπ^-. In addition, the first observation is reported of the decay of the neutral beauty-strange baryon Ξ⁰_b to the D⁰pK^- final state, and a measurement of the Ξ⁰_b mass is performed. Evidence of the Ξ⁰_b→Λ⁺_cK^- decay is also reported.
