Abstract / Bemerkung
We study the high-temperature phase of SU(2) and SU(3) QCD using lattice simulations of an effective 3-dimensional SU(N) + adjoint Higgs-theory, obtained through dimensional reduction. We investigate the phase diagram of the 3D theory, and find that the high-T QCD phase corresponds to the metastable symmetric phase of the 3D theory. We measure the Debye screening mass m(D) with gauge invariant operators; in particular we determine the O(g(2)) and O(g(3)) corrections to mo. The corrections are seen to be large, modifying the standard power-counting hierarchy in high temperature QCD.
