| Summary: | Title screen 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.
