Diffusion matrix associated with conserved charges in relativistic heavy ion collisions

Abstract

Matter produced in heavy ion collisions has multiple conserved numbers like baryon number, strangeness and electric charge. The diffusion process of these charges can be described by a diffusion matrix describing the interdependence of diffusion of different charges. Incorporating the Landau-Lifshitz frame condition, we have estimated the diffusion coefficient matrix using Boltzmann kinetic theory for the hadronic phase within relaxation time approximation.
