The results of an experiment conducted at Fermilab to measure the polarization of the final-state proton in the reaction p+p→p↑+X and p+C→p↑+X are presented. Measurements were made at beam energies of 100, 200, 300, and 400 GeV for PT from 0.5 to 1.5 GeV/c and xF between - 0.7 and - 0.9.

We report measurements of the ratios K+π+, pπ+, K−π−, p¯π−, π−π+, K−K+, and p¯p for hadrons with 0.19<xt<0.62 produced in p−Be and p−W collisions at s=38.8 GeV. The K+π+ ratio at high xt gives the fragmentation-function ratio DuK+Duπ+ at high z. The high-xt K−π− ratio gives an upper limit for DdK−Ddπ− at high z. The pt dependence of pπ+ suggests that scattered constituent diquarks are the primary source of protons with pt<6 GeV/c. We also present species correlations in high-mass h+h− pairs. Strong K+K− and pp¯ correlations were observed.
