We report a measurement of the time-dependent CP-asymmetry parameters S and C in color-suppressed B0→D(*)0h0 decays, where h0 is a π0, η, or ω meson, and the decays to one of the CP eigenstates K+K-, KS0π0, or KS0ω. The data sample consists of 383×106Υ(4S)→BB̄ 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. © 2007 The American Physical Society.
