Description

We have measured the process B±→(K*±→K±π0)π0 with 232x106 Υ(4S)→BB 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*±π0)=[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)
