Abstract
We present improved measurements of the branching fraction and CP asymmetry for the process B-+/-->rho(+/-)pi(0). The data sample corresponding to 211 fb(-1) comprises 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are measured using an extended maximum likelihood fitting method. The branching fraction and CP asymmetry are found to be B(B-+/-->rho(+/-)pi(0))=[10.2 +/- 1.4(stat)+/- 0.9(syst)]x10(-6) and A(CP)(B-+/-->rho(+/-)pi(0))=-0.01 +/- 0.13(stat)+/- 0.02(syst).
