Electrical conductivity of hot and dense QCD matter created in heavy-ion collisions: A color string percolation approach

Recently, transport coefficients, viz., shear viscosity, electrical conductivity, etc., of strongly interacting matter produced in heavy-ion collisions have drawn considerable interest. We study the normalized electrical conductivity (σel/T) of hot QCD matter as a function of temperature (T) using the color string percolation model (CSPM). We also study the temperature dependence of shear viscosity and its ratio with electrical conductivity for the QCD matter. We compare CSPM estimations with various existing results and lattice QCD predictions with (2+1) dynamical flavors. We find that σel/T in CSPM has a very weak dependence on the temperature. We compare CSPM results with those obtained in the Boltzmann approach to multiparton scatterings model. A good agreement is found between CSPM results and predictions of the Boltzmann approach to multiparton scatterings with a fixed strong coupling constant.
