Abstract: (arXiv)

We report a search for the rare decays

B^+ \to D^+ K^0

and

B^+ \to D^+ K^{*0}

in an event sample of approximately 465 million

B\bar B

pairs collected with the BaBar detector at the PEP-II asymmetric-energy

e^+e^-

collider at SLAC. We find no significant evidence for either mode and we set 90\% probability upper limits on the branching fractions of

B(B^+ \to D^+ K^0) < 2.9\times 10^{-6}

and

B(B^+ \to D^+ K^{*0}) < 3.0\times 10^{-6}

.
