We report a search for the rare decays B + → D + K 0 and B + → D + K * 0 in an event sample of approximately 465 × 10 6 B ¯¯¯ B 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 × 10 − 6 and B ( B + → D + K * 0 ) < 3.0 × 10 − 6 .
