  The branching fractions of ${D}_{s}^{\ifmmode\pm\else\textpm\fi{}}$ meson decays serve to normalize many measurements of processes involving charm quarks. Using $586\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for 13 ${D}_{s}^{\ifmmode\pm\else\textpm\fi{}}$ decays in 16 reconstructed final states with a double tag technique. In particular we make a precise me…

  Utilizing the full CLEO-c data sample of $818\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ data taken at the $\ensuremath{\psi}(3770)$ resonance, we update our measurements of absolute hadronic branching fractions of charged and neutral $D$ mesons. We previously reported results from subsets of these data. Using a double tag technique we obtain branching fractions for three ${D}^{0}$ and six ${D}^{+}$ modes, including the reference branching fractions $\mathca…
