Description
We present results on the photoproduction of 10000 charmed particles from the 108 recorded triggers of Fermilab experiment E691. The total cross-section for the photoproduction of D0 and D+ particles (and antiparticles) for xF > 0.2 is measured to be 3.88±0.06±0.40 μb/Be nucleus at = 145 GeV. We have also measured the relative production of different charmed particles, their pT2 and xF distributions and the energy dependence of the total charm cross-section. The mean pT2 is 1.16±0.04 GeV2/c2 and the ratio of charm cross-sections at 200 GeV and 100 GeV is 1.96±0.24. Results of fits to the xF distribution are also reported. (orig.)
