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. Thep t -dependence at low-p t is in agreement with the expectation from geometrical correlation of the valence quarks.
