Abstract A search for baryon-number-violating Ξ0bΞ0b oscillations is performed with a sample of pppp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb11. The baryon number at the moment of production is identified by requiring that the Ξ0bΞ0b come from the decay of a resonance ΞbΞ0bπΞbΞ0bπ or ΞbΞ0bπ, and the baryon number at the moment of decay is identified from the final state using the decays Ξ0bΞ+cπ,Ξ+cpKπ+. No evidence of baryon number violation is found, and an upper limit is set on the oscillation rate of ω<0.08 ps1, where ω is the associated angular frequency.
