Abstract
The nuclear dependence for 800 GeV/c proton production of neutral D me sons has been measured near x(F) = 0 in Experiment 789 at Fermilab. D mesons from beryllium and gold targets were detected with a pair spect rometer and a silicon vertex detector via their decay D --> Kpi. No nu clear dependence is found, with a measured alpha = 1.02 +/- 0.03 +/- 0 .02. The measured differential cross section, dsigma/dx(F), for neutra l-D-meson production at [x(F)] = 0.031 is 58 +/- 3 +/- 7 mub/nucleon. The integrated cross section obtained by extrapolation of the measured cross section to all x(F) is 17.7 +/- 0.9 +/- 3.4 mub/nucleon and is consistent with previous measurements.
