Measurement of Time-Dependent CP-Violating Asymmetries in B0 Meson Decays to eta' KL0
Description
The authors present a preliminary measurement of CP-violating parameters S and C from fits of the time-dependence of B0 meson decays to η'KL0. The data were recorded with the BABAR detector at PEP-II and correspond to 232 x 106 B(bar B) pairs produced in e+e- annihilation through the Υ(4S) resonance. By fitting the time-dependent CP asymmetry of the reconstructed B0 → η'KL0 events, they find S = 0.60 ± 0.31 ± 0.04 and C = 0.10 ± 0.21 ± 0.03, where the first error quoted is statistical and the second is systematic. They also perform a combined fit using both η'KS0 and η'KL0 data, and find S = 0.36 ± 0.13 ± 0.03 and C = -0.16 ± 0.09 ± 0.02
