| Abstract: | We present measurements of the time-dependent C P -violation parameters S and C in B 0 → η ′ K 0 decays. The data sample corresponds to 384 × 10 6 B ¯¯¯ B pairs produced by e + e − annihilation at the Υ ( 4 S ) . The results are S = 0.58 ± 0.10 ± 0.03 and C = − 0.16 ± 0.07 ± 0.03 . We observe mixing-induced C P violation with a significance of 5.5 standard deviations in this b → s penguin dominated mode. |
