Combining all K + K − K 0 events, we find A C P = − 0.015 ± 0.077 ± 0.053 and β eff = 0.352 ± 0.076 ± 0.026     rad , corresponding to a C P violation significance of 4.8 σ . A second solution near π / 2 − β eff is disfavored with a significance of 4.5 σ . We also report A C P and β eff separately for decays to ϕ ( 1020 ) K 0 , f 0 ( 980 ) K 0 , and K + K − K 0 with m K + K − > 1.1     GeV / c 2 .7 p.application/pdfeng(c) American Physical Society, 2007Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5581882019-09-16info:eu-repo/semantics/openAccess
