Description

The cross sections for D0D-bar 0 and D+D- production at 3.773 GeV have been measured with BES-II detector at BEPC. These measurements are made by analyzing a data sample of about 17.3 pb-1 collected at the center-of-mass energy of 3.773 GeV. Observed cross sections for the charm pair production are radiatively corrected to obtain the tree level cross section for DD-bar production. A measurement of the total tree level hadronic cross section is obtained from the tree level DD-bar cross section and an extrapolation of the Ruds below the open charm threshold
