N2 - A search for baryon-number violating Ξb0 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 Ξb0 come from the decay of a resonance Ξb∗-→Ξb0π- or Ξb′-→Ξb0π-, and the baryon number at the moment of decay is identified from the final state using the decays Ξb0→Ξc+π-,Ξc+→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.
