Multiplicity predictions for Pb-Pb collisions at $\sqrt{s} = 5.02$ TeV based on the MC Modified Glauber model

Abstract

We present predictions of the mean multiplicity yields for different centrality classes of Pb-Pb collisions at $\sqrt{s} = 5.02$ TeV at the LHC, obtained using the Monte-Carlo Modified Glauber model (MGM) [1]. Contrary to generally used standard Glauber calculations, the MGM takes into account the energy conservation in the soft particles production. The only one efficient model parameter was tuned and fixed previously (k=0.35) by fitting the available data on multiplicity for all colliding systems up to RHIC energies. The MGM has shown already a good predictive capability for the yields at $\sqrt{s} = 2.76$ TeV, and it is used again within the same MC code for the calculations at $\sqrt{s} = 5.02$ TeV
