Study of thermodynamic observables in Oxygen + Oxygen collisions at sNN = 7 TeV using color string percolation approach

Abstract

The Large Hadron Collider (LHC) at CERN has a plan to have Oxygen–Oxygen (O+O) collisions at [Formula: see text][Formula: see text]TeV collision energy in the forthcoming run. As the system size of [Formula: see text] collisions has the final state multiplicity overlap with those produced in PbPb, p+Pb, and pp collisions, it becomes exciting to study thermodynamic quantities using the Color String Percolation Model (CSPM). The thermodynamic quantities like temperature, shear viscosity to entropy density ratio, and trace anomaly are obtained from the soft region of the transverse momentum spectra of O+O collisions at [Formula: see text][Formula: see text]TeV. The percolation approach within CSPM can be successfully used to describe the initial stages in high-energy heavy ion collisions in the soft region in high-energy heavy ion collisions. The obtained results for O+O collisions are compared with the published results from pp and AA collisions using ALICE data.
