Abstract: Experiments as the ALICE and LHCb at CERN and STAR and PHENIX at Brookhaven Lab show that the quark-gluon plasma behaves like a liquid of very low viscosity, but obeys an equation-of-state very similar to an ideal gas. Chernodub, Verschelde and Zakharov (Theor.Math.Phys., v170, p211-216, 2012) noticed that a model which incorporates both of these properties is the liquid of two components of Landau. On the other hand, it is expected that the above mentioned properties of the quark-gluon plasma emerge from QCD. Inspired by this, we perform a Lattice simulation of a Gauge theory with SU(2) symmetry and compute auto-correlations of the Energy-Momentum tensor. According to Chernodub et al., this can be used to verify if the theory can be modelled by the Landau liquid. We will present preliminary results for the auto-correlations of the Energy-Momentum tensor at zero temperature, which is our staging ground to go to finite temperature.
