The data sample corresponds to the full BABAR dataset of 467 × 10 6 B ¯¯¯ B pairs produced at the PEP-II asymmetric-energy e + e − collider at the Stanford Linear Accelerator Center. The results are S ω K 0 S = 0.55 + 0.26 − 0.29 ± 0.02 , C ω K 0 S = − 0.52 + 0.22 − 0.20 ± 0.03 , S η ′ K 0 = 0.57 ± 0.08 ± 0.02 , C η ′ K 0 = − 0.08 ± 0.06 ± 0.02 , S π 0 K 0 S = 0.55 ± 0.20 ± 0.03 , and C π 0 K 0 S = 0.13 ± 0.13 ± 0.03 , where the first errors are statistical and the second systematic. These results are consistent with our previous measurements and the world average of sin  2 β measured in B 0 → J / ψ K 0 S .16 p.application/pdfeng(c) American Physical Society, 2009Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5777622019-04-05info:eu-repo/semantics/openAccess
