Abstract
We present the first observation of the decay B+->rho K-+(0), using a data sample of 348 fb(-1) collected at the Upsilon(4S) resonance with the BABAR detector. The branching fraction and charge asymmetry are measured to be (8.0(-1.3)(+1.4)+/- 0.6)x10(-6) and (-12.2 +/- 16.6 +/- 2.0)%, respectively, where the first uncertainty is statistical and the second is systematic. The charge asymmetry is defined by A(ch)=(Gamma(-)(B)-Gamma(+)(B))/(Gamma(-)(B)+Gamma(+)(B)) with Gamma(+/-)(B) the B-+/- decay rate. The significance of the observed branching fraction, including systematic uncertainties, is 7.9 standard deviations.
