Abstract
Using a sample of 88.8×106 BB̄ events collected with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center, we measure the branching fractions of seven color-suppressed B-meson decays: β(B̄0→D0π0) = [2.9±0.2(stat)±0.3(syst)]× 10-4, β(B̄0→D*0π0) = [2.9±0.4(stat)±0.5(syst)] × 10-4, β(B̄0→D0η) = [2.5±0.2(stat) ±0.3(syst)]×10-4, β(B̄0→D *0η = [2.6±0.4(stat)δ0.4(syst)] ×10 -4, β(B̄0→D0ω) = [3.0±0.3(stat)±0.4(syst)]× 10-4, β(B̄0→D*0ω) = [4.2±0.7(stat)±0.9(syst)] ×10-4, and β(B̄→D0η′) = [ 1.7±0.4(stat) ±0.2(syst)]× 10-4. We set the 90% confidence-level upper limit: β(B̄0→D*0η′)
