We report a search for the rare decays B(+) -> D(+)K(0) and B(+) -> D(+)K*(0) in an event sample of approximately 465 x 10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at SLAC National Accelerator Laboratory. We find no significant evidence for either mode and we set 90% probability upper limits on the branching fractions of B(B(+) -> D(+)K(0)) < 2.9 x 10(-6) and B(B(+) -> D(+)K*(0)) < 3.0 x 10(-6)

Abstract

We report a search for the rare decays B(+) -> D(+)K(0) and B(+) -> D(+)K*(0) in an event sample of approximately 465 x 10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at SLAC National Accelerator Laboratory. We find no significant evidence for either mode and we set 90% probability upper limits on the branching fractions of B(B(+) -> D(+)K(0)) < 2.9 x 10(-6) and B(B(+) -> D(+)K*(0)) < 3.0 x 10(-6)
