Abstract

We present a study of the decay B-->(D(CP)K-)-K-0 and its charge conjugate, where D-(CP)(0) is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II e(+)e(-) storage ring. We measure the partial-rate charge asymmetries A(CP +/-) and the ratios R-CP +/- of the B ->(DK)-K-0 decay branching fractions as measured in CP +/- and non-CP D-0 decays: A(CP+)=0.35 +/- 0.13(stat)+/- 0.04(syst), A(CP-)=-0.06 +/- 0.13(stat)+/- 0.04(syst), RCP+=0.90 +/- 0.12(stat)+/- 0.04(syst), and RCP-=0.86 +/- 0.10(stat)+/- 0.05(syst).
