| description | We present measurements of the time-dependent CP-violation parameters S and C in the decays B[superscript 0]-->omegaK[subscript S][superscript 0] We present measurements of the time-dependent CP-violation parameters S and C in the decays B0-->omegaK[subscript S][superscript 0], B0-->eta′K[superscript 0], reconstructed as eta′K[subscript S][superscript 0] and η′KL0, and B0-->pi0K[subscript S][superscript 0]. The data sample corresponds to the full BABAR dataset of 467×106 BB[over-bar] pairs produced at the PEP-II asymmetric-energy e[superscript +]e[superscript -] collider at the Stanford Linear Accelerator Center. The results are S[subscript omegaKS0]=0.55-0.29+0.26±0.02, C[subscript omegaKS0]=-0.52-0.20+0.22±0.03, Seta′K0=0.57±0.08±0.02, Ceta′K0=-0.08±0.06±0.02, Spi0KS0=0.55±0.20±0.03, and Cpi0KS0=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 sin2β measured in B0-->J/psiKS0. |
