Abstract
We present a measurement of the branching fractions of the 22 decay channels of the B0 and B+ mesons to D[over-bar][superscript (*)]D[superscript (*)]K, where the D[superscript (*)] and D[over-bar] [superscript (*)] mesons are fully reconstructed. Summing the 10 neutral modes and the 12 charged modes, the branching fractions are found to be B(B0-->D[over-bar] D[over-bar][superscript (*)]D[superscript (*)]K=(3.68±0.10±0.24)% and B(B+-->D[over-bar] D[over-bar][superscript (*)]D[superscript (*)]K=(4.05±0.11±0.28)%, where the first uncertainties are statistical and the second systematic. The results are based on 429 fb[superscript -1] of data containing 471×106BB[over-bar] pairs collected at the Υ(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory.
