The inclusive charge asymmetries of these modes are measured as A C P ( B ± → K ± π + π − ) = 0.032 ± 0.008   ( stat ) ± 0.004   ( syst ) ± 0.007 ( J / ψ K ± ) and A C P ( B ± → K ± K + K − ) = − 0.043 ± 0.009   ( stat ) ± 0.003   ( syst ) ± 0.007 ( J / ψ K ± ) , where the third uncertainty is due to the C P asymmetry of the B ± → J / ψ K ± reference mode. The significance of A C P ( B ± → K ± K + K − ) exceeds three standard deviations and is the first evidence of an inclusive C P asymmetry in charmless three-body B decays. In addition to the inclusive C P asymmetries, larger asymmetries are observed in localized regions of phase space.9 p.application/pdfengcc by (c) CERN; LHCb Collaboration, 2013http://creativecommons.org/licenses/by/3.0/es/Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6290232019-05-16info:eu-repo/semantics/openAccess
