摘要
This Letter describes a study of B meson decays to the pseudoscalar-vector final state ρπ using 31.9×106 BB events collected with the Belle detector at KEKB. The branching fractions B(B+→ρ0π+)=8.0+2.3+0.7−2.0−0.7×10−6 and B(B0→ρ±π∓)=20.8+6.0+2.8−6.3−3.1×10−6 are obtained. In addition, a 90% confidence level upper limit of B(B0→ρ0π0)<5.3×10−6 is reported.
