Abstract

We simulate proton–proton interactions to study densities and multiplicities of charged particles at center-of-mass energy, $\sqrt{s} = 7$ TeV in the forward region and compare predictions with experimental findings of LHCb detector. We use different event generators: Sibyll2.3c, EPOS (1.99 and LHC tunes), and DPMJETIII for the simulations. The kinematic region for momentum $p > 2 GeV / c$ , transverse momentum $p_{T} > 0.2 GeV / c$ and $2.0 < η < 4.8$ in pseudorapidity is kept same as in the LHCb experiment for forward region. Predictions of different models and experimental data are presented and compared as a function of transverse momentum and pseudorapidity.
