A study of the decay B- → D*0K*- based on a sample of 86 × 10 6 υ(4S) → BB̄ decays was presented. The measurement was found to be 2.5 times more precise than previous results. The measurement was based on heavy quark effective theory. The longitudinal polarization fraction of this decay was also measured.
