Abstract
A brief review of the color string percolation model (CSPM) is presented. The clustering of color sources provides a framework of the the partonic interactions in the initial stage of the collisions. The CSPM has described several observables in agreement with the experimental results e.g. multiplicity, elliptic flow at RHIC and LHC energies. The thermodynamical quantities temperature and the Equation Of State (EOS) are obtained in agreement with the Lattice Quantum Chromo Dynamics (LQCD) calculations. The shear viscosity to entropy density ratio (·=s) is obtained at RHIC and LHC energies. It is also observed that the inverse of ·=s is equivalent to trace anomaly ¢ = ( i 3P)=T 4 in excellent agreement with the recent LQCD calculations.
