Abstract

We report on a study of B ⁰ → D(^*)⁰ π⁺π^- decays using 29.1 fb^-1 of e⁺e^- annihilation data recorded at the γ(4S) resonance with the Belle detector at the KEKB storage ring. Making no assumptions about the intermediate mechanism, the branching fractions for B ⁰ → D⁰π⁺π^- and B ⁰ → D^*+π⁺π^- are determined to be (8.0 ± 0.6 ± 1.5) x 10^-4 and (6.2 ± 1.2 ± 1.8) × 10^-4, respectively. An analysis of B ⁰ → D⁰π⁺π^- candidates yields to the first observation of the color-suppressed hadronic decay B ⁰ → D⁰ρ⁰ with the branching fraction (2.9 ± 1.0 ± 0.4) × 10^-4. We measure the ratio of branching fractions Β(B ⁰ → D⁰ρ⁰)/Β(B ⁰ → D⁰ω) = 1.6 ± 0.8.
