| Abstract: | Charged pion production in high energy π-π- interactions is studied in the pT region of 1–2 GeV/c. The characteristics of pion production in π-π- interactions are compared with those in π-p and pp interactions. The pT dependence of pion production in these reactions follows a systematic trend which indicates that high-pT pion production for ππ interactions as well as for πp and pp interactions proceeds via quark-quark scattering as predicted by QCD. |
