(D^\pm}\) and $D^0(\bar{D}^0)$ production asymmetries in $\pi p$ collisions

We use a two-component model to describe the production mechanism of $D$ mesons in $\pi p$ collisions. The model combines the usual QCD processes plus fragmentation and recombination of charm that has been produced by nonperturbative QCD mechanisms. A hard charm component in the pion must be res...

Beschreibung
Zusammenfassung:	We use a two-component model to describe the production mechanism of $D$ mesons in $\pi p$ collisions. The model combines the usual QCD processes plus fragmentation and recombination of charm that has been produced by nonperturbative QCD mechanisms. A hard charm component in the pion must be responsible of the particle anti-particle production asymmetries observed.
