Abstract

We report on the production of J/ψ mesons in 530 and 800 GeV/c pBe collisions in the Feynman-x range 0.0<xF<0.6. The J/ψ mesons were detected via decays into μ+μ-. Differential distributions for J/ψ production have been measured as functions of xF, pT2, and the cosine of the Gottfried-Jackson decay angle. These distributions are compared with results on J/ψ production obtained in 515 GeV/c π-Be collisions, measured by the same experiment, as well as with results from other experiments using incident protons.
