High Temperature 3 D QCD : Dimensional Reduction at Work
We investigate the three-dimensional SU(3) gauge theory at finite temperature in the framework of dimensional reduction. The large scale properties of this theory are expected to be conceptually more complicated than in four dimensions. The dimensionally reduced action is computed in closed analytical form. The resulting effective two-dimensional theory is studied numerically both in the electr...
متن کاملDimensional Reduction at High Temperature Revisited
We give a perturbative analysis of dimensional reduction in the infinite-temperature limit of thermal field theory in the imaginary time formalism. In analogy with the ordinary (Appelquist-Carazzone) decoupling theorem, we seek a class of renormaliza-tion schemes in which the heavy (non-static) modes decouple. This class turns out to consist of temperature-dependent schemes, so that the appropr...
متن کاملDimensional Reduction at High Temperature for Fermions
The concept of dimensional reduction in the high temperature regime is generalized to static Green’s functions of composite operators that contain fermionic fields. The recognition of a natural kinematic region where the lowest Matsubara modes are close to their mass-shell, and the ultraviolet behavior of the running coupling constant of the original theory are crucial for providing the necessa...
متن کاملLimitations to Dimensional Reduction at High Temperature
The claim that renormalizable four-dimensional field theories in the infinite-temperature limit undergo a reduction to effective three-dimensional ones is analyzed in perturbation theory. An essential ingredient is the finite-temperature renormalization group in the imagina~'-time formalism. A precise criterion for the occurrence of complete dimensional reduction is given. This is satisfied onl...
متن کاملPerturbative Qcd at High Temperature
Recent developments of perturbation theory at finite temperature based on effective field theory methods are reviewed. These methods allow the contributions from the different scales to be separated and the perturbative series to be reorganized. The construction of the effective field theory is shown in detail for φ4 theory and QCD. It is applied to the evaluation of the free energy of QCD at o...
