Abstract
We have measured the process B+/-->(K*+/--> K(+/-)pi(0))pi(0) with 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a signal yield of 89 +/- 26 events we obtain the branching fraction B(B+/--> K(*+/-)pi(0))=[6.9 +/- 2.0(stat)+/- 1.3(syst)]x10(-6) with a statistical significance of 3.6 standard deviations including systematic uncertainties, and a charge asymmetry of 0.04 +/- 0.29(stat)+/- 0.05(syst).File in questo prodotto:
