The measurement is performed in six bins of invariant mass squared of the μ + μ − pair, excluding the J / ψ and ψ ( 2 S ) resonance regions. Production and detection asymmetries are removed using the B 0 → J / ψ K * 0 decay as a control mode. The integrated C P asymmetry is found to be − 0.072 ± 0.040 ( stat ) ± 0.005 ( syst ) , consistent with the standard model.8 p.application/pdfengcc by (c) CERN; LHCb Collaboration, 2013http://creativecommons.org/licenses/by/3.0/es/Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6196432019-05-20info:eu-repo/semantics/openAccess
