Understanding the QCD medium by the diffusion of charm quarks using a Color String Percolation Model

Abstract

We study the drag and diffusion coefficients of the charm quark in the deconfined matter produced in the ultra-relativistic collisions by taking the Color String Percolation Model (CSPM) approach. CSPM, being a QCD-inspired model, can give us essential information about the hot and dense system produced in ultra-relativistic collisions. With the information on initial percolation temperature and percolation density, we estimate the relaxation time (${\tau }_c$), drag coefficient ($\gamma$), transverse momentum diffusion coefficient ($B_0$), and spatial diffusion coefficient ($D_s$) of charm quark inside a deconfined medium. Finally, we compare the obtained results with lattice QCD and with various other theoretical models. A good agreement can be observed between the results obtained from CSPM and lattice QCD.
