Abstract

We present improved measurements of the branching fractions of the color-suppressed decays B̄0→D(*)0h0, where h0 represents a light neutral meson π0, η or ω. The measurements are based on a data sample of 140fb-1 collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider, corresponding to 7 times the luminosity of the previous Belle measurements. All the measured branching fractions fall in the range 1.4-2.4×10-4, which is significantly higher than theoretical predictions based on naive factorization.
