Abstract
We report on searches for B--> D(s)(*-)phi and B--> D-s*(-)phi. In the context of the standard model, these decays are expected to be highly suppressed since they proceed through annihilation of the b and (u) over bar quarks in the B- meson. Our results are based on 234 x 10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at SLAC. We find no evidence for these decays, and we set Bayesian 90% confidence level upper limits on the branching fractions B(B--> D(s)(-)phi)< 1.9x10(-6) and B(B--> D-s*(-)phi)< 1.2x10(-5). These results are consistent with standard model expectations.
