Ammar, R. ; Ball, R.C. ; Banerjee, S. ; et al.
Phys.Rev.Lett. 61 (1988) 2185-2188, 1988.
Inspire Record 269400 DOI 10.17182/hepdata.20142

We report on a study of the inclusive production properties of DD¯ mesons in pp collisions at 800 GeV/c and compare our results to measurements made at lower energies and to the expectations of the QCD fusion model.

Inclusive Charm Cross-Sections in 800-GeV/c p p Interactions

The LEBC-MPS collaboration Ammar, R. ; Banerjee, S. ; Baland, J.F. ; et al.
Phys.Lett.B 183 (1987) 110, 1987.
Inspire Record 233423 DOI 10.17182/hepdata.42573

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 +22 μ b (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.
