Abstract

We report a measurement of the branching fraction for the decay B+ρ+π0 based on a 140fb1 data sample collected with the Belle detector at the KEKB asymmetric e+e collider. We measure the branching fraction B(B+ρ+π0)=(13.2±2.3(stat)1.9+1.4(syst))×106, and the CP-violating asymmetry ACP(Bρπ0)=0.06±0.17(stat)0.05+0.04(syst).
