Approach to scaling in inclusive π+- ratios at 147 GeV/c

Published

Journal Article

The ratio of hadronic π+/π- production has been studied in the target fragmentation region of π+p, π-p, K+p and p p collisions at 147 GeV/c beam momentum. The difference between this ratio in the π+p and π-p data is less than at lower energies but still present. No difference exists anymore for the π+/π- ratio at this energy between K+p and pp collisions. Exclusion of diffraction dissociation and resonance production does not change the main conclusions. The energy dependence of the ratio for π+p and π-p collisions gives evidence for a universal asymptotic ratio for all beams. The pt-dependence at low-pt is in agreement with the expectation from geometrical correlation of the valence quarks. © 1982 Springer-Verlag.
