Abstract
We simulate proton-proton interactions to study densities and multiplicities of charged particles at center-of-mass energy, root 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 < eta < 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.
