Soft color interactions in non-perturbative QCD

Improved understanding of non-perturbative QCD dynamics can be obtained in terms of soft color exchange models. Their essence is the variation of color string-field topologies giving a unified description of final states in high energy interactions. In particular, both events with and without large rapidity gaps are obtained in agreement with data from ep at HERA and p anti p at the Tevatron, where also the surprisingly large production rate of high-pperp charmonium and bottomonium is reproduced
