### Updated measurements of absolute $D^+$ and $D^0$ hadronic branching fractions and $σ(e^+e^-\to D\overline{D})$ at $E_\mathrm{cm} = 3774$ MeV

Abstract:

Utilizing the full CLEO-c data sample of 818 pb$^{-1}$ of $e^+e^-$ data taken at the $\psi(3770)$ resonance, we update our measurements of absolute hadronic branching fractions of charged and neutral $D$ mesons. We previously reportedresults 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 $\mathcal{B} (D^0\to K^-\pi^+)=(3.934 \pm 0.021 \pm 0.061)\%$ and \$\mathcal{B} (D^+ \to...
