Temperature dependence of shear viscosity of SU(3)-gluodynamics within lattice simulation
This report is devoted to the study of temperature dependence of shear viscosity in SU(3)-gluodynamics. To calculate shear viscosity we measured the correlation function of the energy-momentum tensor T12T12 for a set of temperatures in the region T/Tc ϵ (0.9, 1.5). The measurements were carried out...
