|The spatial string tension, a classic non-perturbative
probe for the convergence of the weak-coupling
expansion at high temperatures, can be determined in full
QCD as as in a dimensionally reduced effective theory.
Comparing both approaches, we find surprisingly good
almost down to the critical temperature of the
deconfinement phase transition.
