TL;DR: A study of the inclusive production properties of D/D-bar mesons in pp collisions at 800 GeV/c and comparisons to measurements made at lower energies and to the expectations of the QCD fusion model are reported.
Abstract: We report on a study of the inclusive production properties of D/D-bar 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.

TL;DR: In this article, the differential distributions of D mesons produced in 400 GeV/c p-p interactions to the form d 2 σ d x F d p T 2 ∝(1−x F ) n exp [−(p T 2 /〈p T2 〉)] are discussed, and it is suggested that these distributions could reflect contribution of leading di-quarks in pp collisions.

TL;DR: In this paper, a comparative analysis of the global properties of 400 GeV/c proton-proton interactions with and without charm production is presented, where multiplicities, momentum distributions, sphericity and thrust of these interactions are compared.
