Abstract

The transverse momentum (pT) spectra, covering a region of 0.15–10 GeV/c, of charged particles as well as the correlation between the average transverse momentum <pT > and all charged particles (Nch) in pp collision at 900 GeV/c are investigated. Simulations by hadron production models are compared with the measurements of ALICE Collaboration. Qualitatively, all models’ predictions are in good agreement with experimental data for the pT distributions of invariant yield of all charged hadrons. For the <pT > as a function Nch presented in two pT regions, 0.15 < pT < 4 and 0.5 < pT < 4, the EPOS models, and HIJING produced good predictions of the experimental measurements as compared to QGSJETII-04 and Sibyll2.3c. Although the models’ prediction is compatible with the experimental data, none of them is enough comprehensive to provide complete description of all measurements.
