The K+ ratio at high xt gives the fragmentation-function ratio DuK+Du+ at high z. The high-xt K- ratio gives an upper limit for DdK-Dd- at high z. The pt dependence of p+ 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. © 1992 The American Physical Society.journal article10.1103/PhysRevD.45.30302-s2.0-0041725804WOS:A1992HR12600004
