| Résumé : | We report a measurement of the inclusive D/D̄ production cross section in 800 GeV/c proton-proton interactions. The experiment used the high resolution bubble chamber LEBC exposed to an 800 GeV/c proton beam at the Fermilab MPS. We obtain σ(D/ D ̄)=59-15+22μb (statistical errors), having analysed 25% of the total data sample. Comparison with 400 GeV/c pp dat a obtained with LEBC at CERN shows a D/D̄ cross section increase by a factor of 1.7-0.5+0.7. This is in good agreement with fusion model calculations. © 1987. |
