Measurement of Charm-Production Cross Sections in \(e^{+}e^{-}\) Annihilations at Center-of-Mass Energies Between 3.97 and 4.26GeV

Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured charmed-hadron production cross sections for $e^{+}e^{-}$ annihilations at twelve center-of-mass energies between 3.97 and 4.26~GeV. Observed cross sections for the final states $D\bar{D}$, $D^{*}\bar{D}$, $D^{*}\bar{D}^{*}$, $D_{s}\bar{D}_{s}$, $D_{s}^{*}\bar{D}_{s}$, and $D_{s}^{*}\bar{D}_{s}^{*}$ are presented, as well as the total charm cross section. Observed cross sections have been radiatively corrected to obtain tree-level cross sections and $R$.
