Abstract: | A search for baryon-number violating Ξ 0 b oscillations is performed with a sample of p p collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb − 1 . The baryon number at the moment of production is identified by requiring that the Ξ 0 b come from the decay of a resonance Ξ * − b → Ξ 0 b π − or Ξ ' − b → Ξ 0 b π − , and the baryon number at the moment of decay is identified from the final state using the decays Ξ 0 b → Ξ + c π − , Ξ + c → p K − π + . No evidence of baryon-number violation is found, and an upper limit at the 95% confidence level is set on the oscillation rate of ω < 0.08 ps − 1 , where ω is the associated angular frequency. |
