Production asymmetry of D mesons in γp collisions

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. Non perturbative effects are included in terms of a recombination mechanism which gives rise to a production asymmetry.
