2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/225341Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of $D^+$, $D^0$ and $D_s^+$ mesons in $e^{+}e^{-}$ annihilations at thirteen center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charmed mesons ($D\bar{D}$, $D^{*}\bar{D}$, $D^{*}\bar{D}^{*}$, $D_s^+ D_s^-$, $D_s^{*+} D_s^-$, and $D_s^{*+} D_s^{*-}$) and for processes in which the charmed meson pair is accompanied by a pion.8 pages, 8 figures, to be published in the proceedings of CHARM07, Ithaca, NY, August 2007, eConf C070805High Energy Physics - Experimenttext
