Measurement of Time-Dependent CP-Violating Asymmetries in B0 Meson Decays to eta' K0
The BaBar Collaboration, B. Aubert
Abstract
We present a preliminary measurement of CP-violating parameters S and C from fits of the time-dependence of B0 meson decays to eta' K0. The data were recorded with the BaBar detector at PEP-II and correspond to 227 * 106 B-Bbar pairs produced in e+e- annihilation through the Upsilon(4S) resonance. From a maximum likelihood fit we measure the CP-violation parameters S = 0.27 +/- 0.14 (stat) +/- 0.03 (syst) and C = -0.21 +/- 0.10 (stat) +/- 0.03 (syst).
