  "abstract": "<p>We report new measurements of the cross sections for the production of DD\u0304 final states at the \u03c8(3770) resonance. Our data sample consists of an integrated luminosity of 2.93 fb\u22121 of e+e\u2212 annihilation data produced by the BEPCII collider and collected and analyzed with the BESIII detector. We exclusively reconstruct three D0 and six D+ hadronic decay modes and use the ratio of the yield of fully reconstructed DD\u0304 events (\"double tags\") to the yield of all reconstructed D or D\u0304 mesons (\"single tags\") to determine the number of D0D\u03040 and D+D\u2212 events, benefiting from the cancellation of many systematic uncertainties. Combining these yields with an independent determination of the integrated luminosity of the data sample, we find the cross sections to be \u03c3(e+e\u2212 \u2192 D0D\u03040) nb and \u03c3(e+e\u2212 \u2192 D+D\u2212) = (2.830 \u00b1 0.011 \u00b1 0.026) nb, where the uncertainties are statistical and systematic, respectively.</p>",
