Derived Born cross sections of e+e? annihilation into open charm mesons from CLEO-c measurements*

摘要

The exclusive Born cross sections of the production of D0, D+ and mesons in e+e? annihilation at 13 energy points between 3.970 and 4.260 GeV are obtained by applying corrections for initial state radiation and vacuum polarization to the observed cross sections measured by the CLEO-c experiment. Both the statistical and the systematic uncertainties for the obtained Born cross sections are estimated.
