Abstract
The ratio of hadronic π+/π− production has been studied in the target fragmentation region of π+p, π−p,K+p andp 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 betweenK+p andpp 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. Thept -dependence at low-pt is in agreement with the expectation from geometrical correlation of the valence quarks.
