Abstract
We measure the differential cross sections with respect to Feynman x ( X(F)) and transverse momentum (p(T)) for pi, K, and p-induced charm me son production using fully reconstructed D+, D-0, and D-s decays. The shapes of these cross sections are compared to the theoretical predict ions for charm quark production of next-to-leading order perturbative QCD using modern parametrizations of the pion and nucleon parton distr ibutions. We observe the differences expected in production induced by projectiles with different gluon distributions, harder distributions being indicated for mesons than for protons.
