Contribution

It introduces a string percolation framework to describe rapidity-dependent particle densities in various collision types, incorporating energy conservation and multiple scattering effects.

Findings

Particle densities depend on rapidity and collision type.

Model successfully describes data from RHIC and LHC.

Provides insights into the rapidity dependence of particle production.

Abstract

We use multiple scattering and energy conservation arguments to describe $dn/d\eta_{NANA}$ as a function of $dn/d\eta_{pp}$ in the framework of string percolation. We discuss the pseudo-rapidity $\eta$? and beam rapidity Y dependence of particle densities. We present our results for pp, Au- Au, and Pb-Pb collisions at RHIC and LHC.
