Abstract

We report a measurement of the branching fraction for the decay B ⁺ → ρ ⁺π ⁰ based on a 140 fb ^-1 data sample collected with the Belle detector at the KEKB asymmetric e ⁺e ^- collider. We measure the branching fraction B(B ⁺ → ⁺π ⁰) = (13.2 ± 2.3(stat) _-1.9 ⁺(syst)) × 10 ^-6, and the CP-violating asymmetry A _CP(B ^{± ρ} ^±π ⁰) = 0.06 ± 0.17(stat) _-0.05 ^+0.04(syst).
