Abstract

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− → Ξ0b π− or Ξ'b− → Ξ0b π−, and the baryon number at the moment of decay is identified from the final state using the decays Ξ0b → Ξc+ π−, Ξc+ → 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.
