energy-momentum constraints in string production", PHYSICS LETTERS B, 715, 1-3: 230-233.
Abstract: We show that the dependence of the charged particle multiplicity on the
centre-of-mass energy of the collision is, in the String Percolation
Model, driven by the same power law behavior in both proton-proton and
nucleus-nucleus collisions. The observed different growths are a result
of energy-momentum constraints that limit the number of formed strings
at low energy. Based on the very good description of the existing data,
we provide predictions for future high energy LHC runs. (c) 2012
