We present a study of the decay B-→D*0K*- based on a sample of 86×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure the branching fraction B(B-→D*0K*-)=(8.3±1.1(stat)±1.0(syst))×10-4, and the fraction of longitudinal polarization in this decay to be ΓL/Γ=0.86±0.06(stat)±0.03(syst).

Abstract
We present a study of the decay B-→D*0K*- based on a sample of 86×10^6 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure the branching fraction B(B-→D*0K*-)=(8.3±1.1(stat)±1.0(syst))×10-4, and the fraction of longitudinal polarization in this decay to be ΓL/Γ=0.86±0.06(stat)±0.03(syst).
