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