Abstract

We present a preliminary result of the branching fraction for the B meson decay to the final state K⁺pi^-pi⁺ via an intermediate K^*0 resonance using the sample of approximately 23 million B-anti-B mesons produced at the Upsilon(4S) resonance with the BABAR detector at the PEP II e+e- collider. The K^*0 was detected through the decay to the final state K⁺pi^-. The result of this analysis is BF(B⁺ --> K^*0 pi⁺) = (15.5 +/- 3.4 +/- 1.8) x 10^-6 where the first error is statistical and the second is systematic.
