摘要：

A recent investigation has confirmed that the perturbative properties of the deconfined phase of non-abelian Yang-Mills theories at intermediate distances are shared by a renormalizable three-dimensional field model. This effective model is derived from a zero-momentum expansion of the effective action that is generated by the thermal degrees of freedom. Here we extend the investigation of the model beyond the perturbative horizon. For the example of the gauge group SU(2) it is shown that the infrared range accessible by Monte Carlo simulations is well described at least for temperatures above three times the deconfining phase transition temperature. This confirms on a non-perturbative level that dimensional reduction to a local field theory is realized at high temperature.
