Abstract
We investigate the contribution
of the charm-anticharm ($c{\bar c}$) asymmetry of the proton eigenstate
obtained from QCD lattice gauge
to the asymmetry of $D^+,D ^-$ and $D^0,{\bar D}^0$ mesons produced
in $pp$ collisions at large Feynman variables $x$.
Predictions for the asymmetry as function of $x$
for different probabilities of intrinsic charm ({\it IC}) in proton are presented.
