Particle ratios of high x(t) hadrons in p A interactions at s**(1/2) = 38.8-GeV.

Straub, P.B. ; Jaffe, D.E. ; Glass, H.D. ; et al.

Phys.Rev.D 45 (1992) 3030-3037, 1992.

https://inspirehep.net/literature/342598 Inspire Record 342598 DOI 10.17182/hepdata.22727 https://doi.org/10.17182/hepdata.22727

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.
