Utilizing the full CLEO-c data sample of 818pb-1 of e+e- data taken at the ψ(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 D0 and six D+ modes, including the reference branching fractions B(D0→K-π+)=(3.934±0.021±0.061)% and B(D+→K-π+π+)=(9.224±0.059±0.157)%. The uncertainties are statistical and systematic, respectively. In these measurements we include the effects of final-state radiation by allowing for additional unobserved photons in the final state, and the systematic errors include our estimates of the uncertainties of these effects. Furthermore, using an independent measurement of the luminosity, we obtain the cross sections σ(e+e- →D0D̄0)=(3.607±0.017±0.056)nb and σ(e+e-→D+D- )=(2.882±0.018±0.042)nb at a center of mass energy, Ecm=3774±1MeV. © 2014 American Physical Society.Citation to related work
