Abstract: We study the evolution of the particle density, dn/d eta at fixed eta,
with the beam rapidity Y in the framework of string percolation model.
Our main results are: (i) The width of the ``plateau'' increases
proportionally to Y, (ii) limiting fragmentation is violated, and (iii)
the particle density reduces to a step function. (C) 2012 Elsevier B.V.
