  We investigate the structure of the medium formed in heavy ion collisions
using three different models: the Color String Percolation Model (CSPM), the
Core-Shell-Color String Percolation Model (CSCSPM), and the Color Glass
Condensate (CGC) framework. We analyze the radial distribution function of the
transverse representation of color flux tubes in each model to determine the
medium's structure. Our results indicate that the CSPM behaves as an ideal gas,
while the CSCSPM exhibits a structural phase transition from a gas-like to a
liquid-like structure. Additionally, our analysis of the CGC framework suggests
that it produces systems that behave like interacting gases for AuAu central
collisions at RHIC energies and liquid-like structures for PbPb central
collisions at LHC energies.
