Does the D-/D+ Production Asymmetry Decrease at Large xF?
Abstract
We have applied the meson cloud model to calculate the asymmetries in D and Ds meson production in high-energy Σ--nucleus and π--nucleus collisions. We find a good agreement with recent data. Our results suggest that the asymmetries may decrease at large xF.
