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′)<2. 6×10^-4. The channels B̄→D*⁰η, D*⁰ω, and D⁰η′ are seen with more than five-sigma statistical significance. All of these branching fractions are significantly larger than theoretical expectations based on the "naive" factorization model.
