Dynamics of the deconfinement transition

We estimate the dissipation coefficient Gamma that appears in Ginzburg-Landau-Langevin equations that describe phenomenologically the deconfinement transition in QCD. This is done through the implementation of Glauber dynamics of pure SU(3) lattice gauge theory. The coefficient Gamma is extracted from the short-time exponential growth of the equal time correlation function of the order parameter. Although the absolute determination of Gamma is ambiguous due to the difficulties in relating real time and Monte Carlo time, its relative temperature dependence can be obtained with much less arbitrariness.
