On the energy dependence of the D^+/D^- production asymmetry    [PDF]

E. R. Cazaroto, V. P. Goncalves, F. S. Navarra, M. Nielsen

In this paper we discuss the origin of the asymmetry present in D meson production and its energy dependence. In particular, we have applied the meson cloud model to calculate the asymmetries in D^-/D^+ meson production in high energy p-p collisions and find a good agreement with recent LHCb data. Although small, this non-vanishing asymmetry may shed light on the role played by the charm meson cloud of the proton.
