We report a search for B -> J/psi D decays, based on a sample of 124 x 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II storage ring of the Stanford Linear Accelerator Center. No significant signal is found. We obtain upper limits on the branching fractions of 1.3 x 10(-5) for B-0 -> J/psi(D) over bar (0) and 1.2 x 10(-4) for B+ -> J/psi D+ at 90% confidence level.

Abstract
We report a search for B -> J/psi D decays, based on a sample of 124 x 10(6) B (B) over bar events collected with the BABAR detector at the PEP-II storage ring of the Stanford Linear Accelerator Center. No significant signal is found. We obtain upper limits on the branching fractions of 1.3 x 10(-5) for B-0 -> J/psi(D) over bar (0) and 1.2 x 10(-4) for B+ -> J/psi D+ at 90% confidence level.File in questo prodotto:
