Measurement of time dependent CP asymmetry parameters in B0 meson decays to omegaK_S^0, eta^([prime])K^0, and pi^0K_S^0 (2009)

Abstract

We present measurements of the time-dependent CP-violation parameters S and C in the decays B0-->omegaKS0, B0-->eta[prime]K0, reconstructed as eta[prime]KS0 and eta[prime]KL0, and B0-->pi0KS0. The data sample corresponds to the full BABAR dataset of 467×106 B[overline B] pairs produced at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. The results are SomegaKS0=0.55-0.29+0.26±0.02, ComegaKS0=-0.52-0.20+0.22±0.03, Seta[prime]K0=0.57±0.08±0.02, Ceta[prime]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 sin2beta measured in B0-->J/psiKS0.
