Framework for non-perturbative analysis of a Z(3)-symmetric effective theory of finite temperature QCD

چکیده
We study a three dimensional Z(3)-symmetric effective theory of high temperature QCD. The exact lattice-continuum relations, needed in order to perform lattice simulations with physical parameters, are computed to order O(a0) in lattice perturbation theory. Lattice simulations are performed to determine the phase structure of a subset of the parameter space. [email protected]

We discuss the logarithmic contributions to the vacuum energy density of the three-dimensional SU(3) + adjoint Higgs theory in its symmetric phase, and relate them to numerical Monte Carlo simulations. We also comment on the implications of these results for perturbative and non-perturbative determinations of the pressure of finite-temperature QCD.

Dimensional reduction is a powerful technique to study the high-temperature behaviour of gauge theories. The efficiency of this method was tested in a detailed investigation of the reduction to 2D of (2+1)D QCD [1],[2], showing that it is valid down to temperatures T as low as 1.5 times T c , the critical temperature for deconfinement in (2+1)D. As it is standard, the reduced model was derived ...

متن کاملNon-Perturbative QED and QCD at Finite Temperature
We present results of numerical solutions of Schwinger-Dyson equations for the finite-temperature quark and electron propagators. It is shown that both strongly coupled QED and QCD undergo a chiral symmetry restoring phase transition as the temperature is increased. We go beyond the bare vertex or “rainbow” approximation by applying the finite-temperature Ward-Takahashi identity to constrain th...
