Abstract

From a sample of 232×10^6 Υ(4S)→BB events collected with the BABAR detector at the PEP-II B Factory in 1999–2004, we measure the B-→D^0K^(*-)(892) decay branching fraction using events where the K^(*-) is reconstructed in the K_S^0π^- mode and the D^0 in the K^-π^+, K^-π^+π^0, and K^-π^+π^+π^- channels: B(B^-→D^0K^(*-)(892))=(5.29±0.30(stat)±0.34(syst))×10^(-4).
