Aubert, B. et al. (2005) Evidence for the decay B±→K*±π0. Physical Review D, 71 (11). p. 111101. ISSN 1550-7998

We have measured the process B±→(K*±→K±π0)π0 with 232×106 Υ(4S)→BB̅ 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)]×10-6 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).
