Search for B(sup +) (yields) D(sup +)K(sup 0) and B(sup t) yields D(sup t)K(sup asterisk)(sup 0) Decays

摘要

We report a search for the rate decays B(sup +)(yields)D(sup +)K(sup 0) and B(sup +)(yields)D(sup +)K(sup asterisk)(sup 0) in an event sample of approximately 465 million BB pairs collected with the BABAR detector at the PEP-II asymmetric energy e(sup +)e(sup -) collider at SLAC. We find no significant evidence for either mode and we set 90% probability upper limits on the branching fractions of (ss) (B(sup +)(yields)D(sup +)K(sup 0))
