Abstract:
We have studied the QCD viscosity in the vicinity of confinement/deconfinement transition in lattice simulations. In particular, we have computed with high accuracy the correlators of energy-momentum tensor in gluodynamics in the temperature range T/Tc=(0.9, 1.5). Using these correlation functions, we evaluated the spectral densty. Using it, we finally calculated the viscosity. The results of the calculation are in agreement with the values of viscosity, obtained in the RHIC experiment.
