Abstract

Employing a nonperturbative gauge invariant definition of the Debye screening mass m_D in the effective field theory approach to finite temperature QCD, we use 3D lattice simulations to determine the leading O(g²) and to estimate the next-to-leading O(g³) corrections to m_D in the high temperature region. The O(g²) correction is large and modifies qualitatively the standard power-counting hierarchy picture of correlation lengths in high temperature QCD.
