    Abstract: We report the first observation of color-suppressed B¯0→D0π0, D*0π0, D0η, and D0ω decays, and evidence for B¯0→D*0η and D*0ω. The branching fractions are B(B¯0→D0π0)=(3.1±0.4±0.5)×10−4, B(B¯0→D*0π0)=(2.7+0.8+0.5−0.7−0.6)×10−4, B(B¯0→D0η)=(1.4+0.5−0.4±0.3)×10−4, B(B¯0→D0ω)=(1.8±0.5+0.4−0.3)×10−4, and we set 90% confidence level upper limits of B(B¯0→D*0η)<4.6×10−4 and B(B¯0→D*0ω)<7.9×10−4. The analysis is based on a data sample of 21.3fb−1 collected at the Υ(4S) resonance by the Belle detector at the KEKB e+e− collider.
