Abstract

Using a sample of 232×106Υ(4S)→BB̄ events collected with the BABAR detector at the PEP-II B factory we study the decay B-→[K+π-]DK*- where the K+π- is either from a Cabibbo-favored D̄0 decay or doubly-suppressed D0 decay. We measure two observables that are sensitive to the Cabibbo-Kobayashi-Maskawa angle γ; the ratio R of the charge-averaged branching fractions for the suppressed and favored decays; and the charge asymmetry A of the suppressed decays: R=0.046±0.031(stat) ±0.008(syst), A=-0.22±0.61(stat)±0.17(syst). © 2005 The American Physical Society.
