Evolution of particle density in high-energy pp collisions    [PDF]

I. Bautista, C. Pajares, J. Dias de Deus

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.
