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 meson production using fully reconstructed D+, D-0, and D-s decays. Theshapes of these cross sections are compared to the theoretical predictions for charm quark production of next-to-leading order perturbativeQCD using modern parametrizations of the pion and nucleon parton distributions. We observe the differences expected in production induced by projectiles with different gluon distributions, harder distributionsbeing indicated for mesons than for protons.
