Search for B+ to D+ K(*)0 decays with the BaBar experiment

Abstract

We report a search for the rare decays B+ to D+ K0 and B+ to D+ K*0 in an event sample of approximately 465 million BBbar 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 BF(B+ to D+ K0) < 2.9x 10^-6 and BF(B+ to D+ K*0) < 3.0 x 10^-6.
