Abstract
Using a sample of 232x10(6) Upsilon(4S)-> B (B) over bar events collected with the BABAR detector at the PEP-II B factory we study the decay B-->[K(+)pi(-)](D)K*- where the K(+)pi(-) is either from a Cabibbo-favored (D) over bar (0) decay or doubly-suppressed D-0 decay. We measure two observables that are sensitive to the Cabibbo-Kobayashi-Maskawa angle gamma; 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).
