摘要：

Employing a nonperturbative gauge invariant definition of the Debye screening mass mo in the effective field theory approach to finite temperature QCD, we use 3D lattice simulations to determine the leading O(g(2)) and to estimate the next-to-leading O(g(3)) corrections to m(D) in the high temperature region. The O(g(2)) correction is large and modifies qualitatively the standard power-counting hierarchy picture of correlation lengths in high temperature QCD. [S0031-9007(97)04353-6].
