Abstract

We report a measurement of the time-dependent C P -asymmetry parameters S and C in color-suppressed B 0 → D ( * ) 0 h 0 decays, where h 0 is a π 0 , η , or ω meson, and the decays to one of the C P eigenstates K + K − , K 0 S π 0 , or K 0 S ω . The data sample consists of 383 × 10 6     Υ ( 4 S ) → B ¯¯¯ B decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The results are S = − 0.56 ± 0.23 ± 0.05 and C = − 0.23 ± 0.16 ± 0.04 , where the first error is statistical and the second is systematic.
