The baryon number at the moment of production is identified by requiring that the Ξ 0 b come from the decay of a resonance Ξ * − b → Ξ 0 b π − or Ξ ' − b → Ξ 0 b π − , and the baryon number at the moment of decay is identified from the final state using the decays Ξ 0 b → Ξ + c π − , Ξ + c → 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.9 p.application/pdfengcc by (c) CERN; LHCb Collaboration, 2017http://creativecommons.org/licenses/by/3.0/es/Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6780272019-05-03info:eu-repo/semantics/openAccess
