Distributions of the Transverse Momentum and Pseudorapidity of Charged Particles in pp Collisions at 0.9 TeV

Abstract

We have studied the charged particles spectra for the pseudorapidity region of ∣η∣ < 2.5, the multiplicity of charged particles, its dependence on pT as well as on η and the relation between average pT and charged particles multiplicity in pp collisions at √s = 0.9 TeV. For simulations, we have used the EPOS-LHC, EPOS-1.99, QGSJETII-04, and SIBYLL-2.3c models and compared their predictions with the experimental data of ATLAS experiment. For the pT distribution, predictions of the Sibyll-2.3c are matching with the experimental data in a region of 0.5 GeV/c < pT < 0.8 GeV/c and EPOS-1.99 model results are near to the experimental data for 0.5 GeV/c < pT < 1.5 GeV/c. For the case of average pT, EPOS-LHC, and Sibyll-2.3c predictions are closer to the experimental data. For the pseudorapidity charged particle density distributions, QGSJETII-04 model predictions are better describing the experimental data.
