In this work, we analyze two aspects of the measured data, viz., （i） the pT-spectra of pions, kaons, proton-antiproton at the above-mentioned energies, and （ii） some of their very important ratio behaviors, in the light of a version of the sequential chain model. The agreements between the measured data and the model-based results are generally found to be modestly satisfactory.展开更多
