Improved Measurement of B[superscript +]-->rho[superscript +]rho[superscript 0] and Determination of the Quark-Mixing Phase Angle alpha
We present improved measurements of the branching fraction B, the longitudinal polarization fraction fL, and the direct CP asymmetry ACP in the B meson decay channel B+-->ρ+ρ0. The data sample was collected with the BABAR detector at SLAC. The results are B(B+-->ρ+ρ0)=(23.7±1.4±1.4)×10-6, fL=0...
