We have measured the inclusive production properties of D and D̅ messons produced from pp interactions at √s=27.4 GeV. The differential production cross section is well represented by the empirical form d2σ/dXFdP2T= 1/2[σ(D/D̅)(n=1)b](1-|XF|)η] exp(−bP2T with n=4.9±0.5, b=(1.0±0.1)GeV/c)−2, and the inclusive D/D̅ cross section σD/D̅ is (30.2±3.3) ωb. The QCD fusion model predicts D/D̅ production which is in good agreement with our data except for the magnitude of the cross section which depends sensitively on the assumed mass of the charm quark.
