Abstract.

We discuss the hadroproduction of charmed mesons in the framework of the constituent cascade model taking into account the valence quark annihilation. It is shown that the valence quark annihilation process dominates at large Feynman x regions and explains the recent experimental data on the asymmetry between \(D^0\) and \(\bar{D}^0\) at \(350 {\mathrm{ GeV}}/c\) in \(\pi^-N\) collisions.
