Abstract

In this paper, we study FLRW bulk viscous cosmology in presence of particle creation and obtain the Hubble expansion parameter. In order to find effect of particle creation and bulk viscosity on the cosmological quantities we use perturbation theory and recent lattice QCD simulations. Finally, we obtain the time evolution of energy density for viscous cosmological matter in the presence of particle creation
