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 relationship
between average pT and charged particles multiplicity in pp
collisions at TeV. For simulations, we have used 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<pT<0.8 GeV/c and EPOS-1.99 model results are near to the experimental
data for 0.5<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.
