Rapidity and centrality dependence in the percolating color strings scenario

Abstract

In AA collisions fusion and percolation of colour strings is studied at fixed rapidity y. Distribution of strings in rapidity is obtained from the observed rapidity spectra in pp collisions. For y-dependence of multiplicities in Au-Au collisions good agreement is obtained with the existing experimental data. Predictions for LHC energies coincide with the extrapolation of the data. Agreement with the data of the transverse momentum spectra requires introduction of quenching into the model.
