# Measurement of the branching fraction and polarization for the decay $B^- \to D^{*0}K^{*-}$

Abstract : We present a study of the decay B- -> D*0 K*- based on a sample of 86 million Upsilon(4S) -> BBbar decays collected between 1999 and 2002 with the BaBar detector at the PEP-II asymmetric-energy B-Factory at SLAC. We measure the branching fraction B(B- -> D*0 K*-) = 8.3 +/- 1.1 (stat)} +/- 1.0 (syst) x 10e-4, and the fraction of longitudinal polarization in this decay to be GammaL/Gamma = 0.86 +/- 0.06 +/- (stat) +/- 0.03 (syst).
