Abstract :
We study the production asymmetry of charm versus anticharm mesons in photon–proton interactions. We consider photon–gluon fusion plus higher order corrections in which light quarks through vector meson–proton interactions contribute to the cross section. Nonperturbative effects are included in terms of a recombination mechanism which gives rise to a production asymmetry.
