Abstract: | We present a measurement of the branching fractions of the 22 decay channels of the B 0 and B + mesons to ¯¯¯ D ( * ) D ( * ) K , where the D ( * ) and ¯¯¯ D ( * ) mesons are fully reconstructed. Summing the 10 neutral modes and the 12 charged modes, the branching fractions are found to be B ( B 0 → ¯¯¯ D ( * ) D ( * ) K ) = ( 3.68 ± 0.10 ± 0.24 ) % and B ( B + → ¯¯¯ D ( * ) D ( * ) K ) = ( 4.05 ± 0.11 ± 0.28 ) % , where the first uncertainties are statistical and the second systematic. The results are based on 429 fb − 1 of data containing 471 × 10 6 B ¯¯¯ B pairs collected at the Υ ( 4 S ) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. |
