Abstract
We report evidence for the decays B-0-->D(s)(+)pi(-) and B-0-->Ds-K+ and the results of a search for B-0-->D*(+)(s)pi(-) and B-0-->D*K--(s)+ in a sample of 84x10(6) Y(4S) decays into B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. We measure the branching fractions B(B-0-->D(s)(+)pi(-))=[3.2+/-0.9(stat)+/-1.0(syst)]x10(-5) and B(B-0-->Ds-K+)=[3.2+/-1.0(stat)+/-1.0(syst)]x10(-5). We also set 90% C.L. limits B(B-0-->D*(+)(s)pi(-))<4.1x10(-5) and B(B-0-->D*K--(s)+)<2.5x10(-5).
