We present measurements of the time-dependent CP-violation parameters S and C in the decays B(0) -> omega K(S)(0), B(0) -> eta'K(0), reconstructed as eta'K(S)(0) and eta'K(L)(0), and B(0) -> pi(0)K(S)(0). The data sample corresponds to the full BABAR dataset of 467 x 10(6) B (B) over bar pairs produced at the PEP-II asymmetric-energy e(+)e(-) collider at the Stanford Linear Accelerator Center. The results are S(omega KS0) = 0.55(-0.29)(+0.26) +/- 0.02, C(omega KS0) = 0.52(-0.20)(+0.22) +/- 0.03, S(eta'K0) = 0.57 +/- 0.08 +/- 0.02, C(eta'K0) = 0.08 +/- 0.06 +/- 0.02, S(pi 0KS0) = 0.55 +/- 0.20 +/- 0.03, and C(pi 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 sin2 beta measured in B(0) -> J / psi K(S)(0).

Abstract

We present measurements of the time-dependent CP-violation parameters S and C in the decays B(0) -> omega K(S)(0), B(0) -> eta'K(0), reconstructed as eta'K(S)(0) and eta'K(L)(0), and B(0) -> pi(0)K(S)(0). The data sample corresponds to the full BABAR dataset of 467 x 10(6) B (B) over bar pairs produced at the PEP-II asymmetric-energy e(+)e(-) collider at the Stanford Linear Accelerator Center. The results are S(omega KS0) = 0.55(-0.29)(+0.26) +/- 0.02, C(omega KS0) = 0.52(-0.20)(+0.22) +/- 0.03, S(eta'K0) = 0.57 +/- 0.08 +/- 0.02, C(eta'K0) = 0.08 +/- 0.06 +/- 0.02, S(pi 0KS0) = 0.55 +/- 0.20 +/- 0.03, and C(pi 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 sin2 beta measured in B(0) -> J / psi K(S)(0).
