We present results on the production of omega mesons at high transverse momenta in pi^-Be interactions at 515 GeV/c. The data span the kinematic range 3.5 < p_T < 8 GeV/c. We compare the measured cross section with expectations from Monte Carlo QCD generators. The relative yield of omega to pi^0 mesons is used to extract the ratio of vector to pseudoscalar meson production for the first generation of quarks.

We report on the production of J/psi mesons in 530 and 800 GeV/c proton - Be collisions in the Feynman-x range 0.0 < xf < 0.6. The J/psi mesons were detected via decays into opposite sign muon pairs. Differential distributions for J/psi production have been measured as functions of xf, pT^2, and cosine of the Gottfried-Jackson decay angle. These distributions are compared with results on J/psi production obtained in 515 GeV/c pion - Be collisions, measured by the same experiment, as well as with results from other experiments using incident protons.
