Model predictions of charge particle densities and multiplicities in the forward region at 7 TeV

Abstract

We simulate proton–proton interactions to study densities and multiplicities of charged particles at center-of-mass energy, [Formula: see text] 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 [Formula: see text], transverse momentum [Formula: see text] and [Formula: see text] 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.
