We report a search for the rare decays B+→D+K0 and B+→D+K*0 in an event sample of approximately 465×106 BB̅ 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+K0)<2.9×10-6 and B(B+→D+K*0)<3.0×10-6.

Abstract
We report a search for the rare decays B+→D+K0 and B+→D+K*0 in an event sample of approximately 465×106 BB̅ 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+K0)<2.9×10-6 and B(B+→D+K*0)<3.0×10-6.File in questo prodotto:
