Light Hadron Production in Proton–Proton Collisions at Different LHC Energies: Measured Data versus a Model

  • Experiments involving proton–proton collisions at energies √sNN=0.9, 2.76 and 7 TeV in the large hadron collider produce a vast amount of high-precision data. 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.
