Abstract
Decays of beauty baryons to the and final states (where indicates a pion or a kaon) are studied using a data sample of collisions, corresponding to an integrated luminosity of , collected by the LHCb detector. The Cabibbo-suppressed decays and are observed, and their branching fractions are measured with respect to the decays and . In addition, the first observation is reported of the decay of the neutral beauty-strange baryon to the final state, and a measurement of the mass is performed. Evidence of the decay is also reported.
