Abstract

We present measurements of the time-dependent CP-violation parameters S and C in the decays B0→ωKS0, B0→η′K0, reconstructed as η′KS0 and η′KL0, and B0→π0KS0. The data sample corresponds to the full BABAR dataset of 467×106 BB̅ pairs produced at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. The results are SωKS0=0.55-0.29+0.26±0.02, CωKS0=-0.52-0.20+0.22±0.03, Sη′K0=0.57±0.08±0.02, Cη′K0=-0.08±0.06±0.02, Sπ0KS0=0.55±0.20±0.03, and Cπ0KS0=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⁡2β measured in B0→J/ψKS0.
