Abstract

The ratio R of inclusive π⁺ π^- production at low transverse momenta is measured in π⁺ n and pn interactions at 195 GeV/c.R ( 1 R) in the proton (neutron) fragmentation region increases with Feynman-x and is smaller than R from π⁺ fragmentation. The results agree with a quark-quark scattering model originally proposed for "hard" processes and disagree with a modified version of the model which includes gluon scattering.
