    A search for baryon-number violating Ξ0b oscillations is performed with a sample of pp 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 Ξ0b come from the decay of a resonance Ξ*b- → Ξ0bπ- or Ξ'b- → Ξ0bπ-, and the baryon number at the moment of decay is identified from the final state using the decays Ξ0b → Ξ+cπ-, Ξ+c → pK-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.
