Abstract
We present the measurement of the ratios of branching fractions B... to B..., and B... to B... We analyze data taken with the CDF II detector that corresponds to an integrated luminosity of 355 pb - 1 in pp collisions at ... TeV at the Fermilab Tevatron. Using a novel displaced track trigger we reconstruct 494 ± 28 B... decays, 8098 ± 114 B... decays, 159 ± 17 B... decays, and 3288 ± 76 B... decays. Using the world average value of the ... production ratio fs/fd = 0.259 ± 0.038, we determine the ratios of branching fractions ... where the uncertainties labeled BR and PR refer to the uncertainty on the D meson branching fractions and the production ratio fs/fd, respectively.
