摘要：

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.
