摘要

The Large Hadron Collider (LHC) at CERN has a plan to have Oxygen–Oxygen (O+O) collisions at \(\sqrt{{s}_{NN}}=7\) TeV in the forthcoming run. As the system size of O+O collisions have the final state multiplicity overlap with those produced in Pb+Pb, p+Pb, and pp collisions, it becomes exciting to study thermodynamic quantities using the Color String Percolation Model (CSPM). The thermodynamic quantities like percolation density factor, color suppression factor, temperature, shear viscosity to entropy density ratio and trace anomaly are obtained from soft region of the transverse momentum spectra of O+O collisions at \(\sqrt{{s}_{NN}}=7\) TeV. The percolation approach within CSPM can effectively describe the initial stages of high energy heavy ion collisions in the soft region. The obtained results for O+O collisions are compared with the published results from pp and A-A collisions using ALICE data.
