Abstract

We present measurements of the time-dependent CP-violation parameters S and C in the decays B0→ÏKS0, B0→ωK0, reconstructed as ωKS0 and ωKL0, and B0→Ï€0KS0. The data sample corresponds to the full BABAR dataset of 467Ö106 BB- pairs produced at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. The results are SÏKS0=0.55-0.29+0.26±0.02, CÏKS0=-0.52-0.20+0.22±0.03, SωK0=0.57±0. 08±0.02, CωK0=-0.08±0.06±0.02, SÏ€0KS0=0.55±0.20±0.03, and CÏ€0KS0=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 sina 2 measured in B0→J/ KS0.
